I wear it every day, it's comfortable and looks stylish.

Why copper works
Kills bacteria on contact
Changes the water it touches
A mineral your body needs
Long used for skin and recovery
Bold on the wrist
The hammered surface gives the wide bangle a striking, handcrafted rhythm. Against the skin, it feels just as bold as it looks.
Hand-worked
Every small dent was made by hand, so no two bangles carry exactly the same pattern. You can see this bold, handcrafted character from every side.
What you actually get
Wearing a copper bracelet is not a new idea. The practice runs from Egyptian and Greek sources through Ayurveda to the modern Western market, and it was also studied seriously a few times in the twentieth century. What those studies did and did not show is set out in the copper bracelet, a centuries-old tradition.
There are four finishes. Twisted has a classic cable structure of strands wound into each other. Smooth is a single, even band with no relief. Hammered is worked by hand and catches the light in small facets. Round is a plain round bar with no texture. The copper is the same in all four; the choice is about how visibly you want to wear it.
The bracelet is open and adjustable, with a circumference of about 17.5 centimetres. You bend it slightly wider or narrower with two hands so it stays on the wrist without pinching. Do that gently and no more often than you need to: copper is malleable, but bending it back and forth repeatedly weakens the metal.
What to watch out for
Take the bracelet off when you shower, swim and exercise. Soap, chlorine and sweat speed up the darkening, and that is the one thing that makes wearing it unpleasant over time.
On many wearers, copper leaves a faint green tint on the skin. That is a reaction between copper, sweat and skin oils, and it washes off with water. What it does and does not mean is explained in why is my copper turning green or black.
We make no health claims about wearing copper on the skin. What may officially be said about copper in the EU, and what that rests on, is set out in the eight official EU claims.
How it arrives
You unpack a sturdy branded box with a Kopero card inside: the QR code on it takes you to the digital manual. A velvet pouch comes with it too, to keep things protected on the move or in the cupboard.
What makes this special
Solid copper against the skin
Nickel-free and uncoated, so the metal can react directly with air, moisture and skin contact.
Four characters, one material
Twisted, smooth, hammered or round: the same copper quality, each with a different texture and look.
A long tradition of wear
In the oldest clinical study (Walker and Keats, 1976), copper bracelets released an average of 13 milligrams of copper per month through the skin.
Open, adjustable cuff
You slide the bracelet over your wrist instead of clasping it shut. Bend the ends carefully and as little as possible when adjusting it.
A colour change that comes with pure copper
Solid copper changes colour a little on its own as you wear the bracelet. That's completely normal, and even a sign of pure copper. If you prefer the shine, simply polish the bracelet with lemon and salt. Exactly how is in the care guide.
99.21% copper, measured independently
The material is analysed by RTC Laboratory in Moradabad, a NABL-accredited lab, tested to ASTM-1621 and IS-228. The measurement came out at 99.21% copper and 0.75% zinc. That zinc is not an additive but a residue of the casting process: it makes the copper marginally stronger and changes nothing else. Food safety is covered by a second report, from URS Products and Testing, tested against EC 1935/2004, EU 10/2011 and REACH.

One bangle, four characters
Solid, uncoated copper, shaped as an open bangle and available in four distinctive finishes.
The bangle is made from copper you see and feel directly, with no lacquer sealing the material off.
The two ends complete the classic open bangle shape.
From striking texture to a calm profile: each style gives the same material a different character.
The bangle arrives carefully packaged in a Kopero jewellery box with a soft storage pouch.

Around your wrist in six steps
From adjusting the size to wearing it every day. The bracelet is an open cuff: you slide it around your wrist instead of clasping it shut.
-
1
Polish it once before you start
That way you begin with a clean, even shine and watch the patina form from the start.
-
2
Adjust the size
Hold the bracelet with both hands and slowly bend the ends slightly further apart or closer together. Do this as little as possible: copper only tolerates a limited number of bends.
-
3
Slide it over your wrist
Turn the opening towards the inside of your wrist, slide the bracelet over and turn it back. It should stay in place without pinching.
-
4
Take it off for water and soap
Swimming, showering, exercise and cleaning: take the bracelet off for those. Chlorine, soap and sweat speed up tarnishing.
-
5
A green film on your skin
Copper reacts with moisture and salts in sweat to form a thin, greenish layer. It's harmless and washes off again with water and a cloth.
-
6
Polish it or leave it be
If you want shine, polish with lemon and salt and dry right away. If you want to keep the dark patina, do nothing. Store the bracelet in the velvet pouch.
The packaging also carries a QR code that takes you straight to this guide.
Reviews of this product
Sleek and timeless design, exactly my taste.
Beautiful craftsmanship, feels really luxurious.
Comfortable and subtle, I wear it day and night.
I bought it because I'd read that copper can be good for the skin and for energy. Whether it really works that way I don't know, but I feel noticeably less sluggish at the end of the day.
My wrist often felt stiff after computer work. With this bracelet I have less of that. Maybe it's all in my head, fine by me, I'm happy with it.
Wow, this one really feels powerful. As soon as I put it on my skin warms up underneath, and after an hour I feel more calm in my body.
I don't sleep in it, but I wear it during the day. My energy feels steadier and the afternoon dip is smaller.
The twisted strands make a lot of contact with my skin. Since wearing it, the skin around my wrist feels less dry. That was the real surprise.
The twisted structure looks handcrafted and catches the light beautifully.
Bought out of curiosity about copper's traditional use. After two weeks my arm felt less heavy. I hadn't expected a difference that quickly.
My husband wanted to try it too and now wears it himself. He says his hands feel more supple in the morning. So we ordered a second one.
The first few days I noticed nothing. Then I realised I still had energy left after a long working day. Not suddenly wired, just less drained.
The copper warms up quickly on my skin and that pleasant feeling stays for hours. That's exactly why I wear it almost every day.
Bent it gently to size once, and it has fitted perfectly ever since.
I put it on during meditation and feel a kind of warmth along my forearm. Hard to explain, but it helps me settle faster.
I'd read about copper and joints and thought: it can't hurt to try. After a month my wrist genuinely feels looser. I'm honestly surprised by that. In the first week I deliberately kept track of when my wrist felt restless. That happened less and less often. So the bracelet stays on, even though I can't explain exact...
The warm copper tone pairs easily with my watch and leather bracelet.
Lovely gift packaging, and the bracelet looked even better in real life than in the photo.
After a few days of wearing it I noticed my hands stayed warmer. Especially on colder mornings I find that very pleasant.
I was mainly curious about the effect on my energy. Not spectacular, but noticeable: I'm less worn out at the end of the working day.
The smooth band sits broadly against the skin and warms up quickly. To me that feels calming, almost like having a small warm compress on my wrist all the time.
My skin reacts very calmly to this copper. The bracelet feels warm, comfortable and pleasant for everyday wear.
Since wearing it I move my wrist more freely and have to think about it less while working. I really do notice a difference.
The smooth version is understated, modern and very easy to combine.
I'd read that copper is traditionally worn for balance. That sounded rather vague, yet my head feels calmer when I have it on. Remarkable.
Sometimes I forget it in the morning and then I really miss something. Not a tingle as such, more a steady feeling through the day.
Wow, within a week my wrist felt more supple during yoga. The bracelet doesn't get in the way during the poses either.
My mother has sworn by copper for years. Now I understand why she's so enthusiastic. I feel more warmth and less tension in my hand.
After a quick adjustment the bracelet stayed comfortably in place all day.
I wear it on busy days and get the impression I'm less rushed. It may sound woolly, but this is my experience.
After a month: fewer cold fingers and a wrist that nags less after typing. Really very happy with it. I didn't want to convince myself too quickly, so I wore it every other day. On the days without, what I missed most was the warmth. Now I reach for it automatically while getting dressed.
I deliberately let the natural colour change happen, which makes it more personal over time.
Subtle enough for the office and still clearly different from standard jewellery.
I feel warmth under the bracelet fairly quickly and it spreads into my hand. On cold days that's really nice.
Bought because of the stories about copper and energy. I'm usually not one for this sort of thing, but my afternoon dip is nearly gone. Wow.
I put it back on after exercising and my wrist quickly feels calm and supple. That moment has become part of my routine.
The hammered facets touch the skin differently from a smooth band. To me that gives a gentle tingle and makes me feel more alert.
After two weeks my partner remarked that I complained less about cold hands. I hadn't even consciously noticed the change myself.
The hammered surface shimmers softly and makes every part of the band slightly different.
My skin feels calm under the bracelet and the copper warms up pleasantly fast. Very comfortable.
I wear this during my breathing exercises. The warm copper helps me stay with my body instead of in my head.
I'd read that copper is traditionally worn for supple joints. My hand feels looser, and that's a really good experience for me.
After a few weeks my wrist felt more and more supple. The bracelet now lives next to my keys and I put it on automatically.
The texture hides marks of use nicely and gives the bracelet a rugged look.
Powerful look and, for me, a powerful feeling too. More energy, especially in the morning.
The skin under the bracelet feels less tight than under my steel watch. I hadn't expected that from copper. My watch often left a clammy feeling; this doesn't. The copper warms up without getting stuffy. For me that's the biggest difference.
It sat well straight away once I'd adjusted it to my wrist.
The patina deepens the pattern and makes it lovelier week by week.
The round band rests very directly along two lines of my skin. Within half an hour the copper warms up and I feel my hand relax.

Frequently asked questions about this product
How do I adjust the size of the bracelet?
Hold the bracelet with both hands and slowly bend the open ends slightly further apart or closer together, until it sits comfortably on your wrist without pinching. Do this as little as possible: copper only tolerates a limited number of bends, so adjust the size in small steps rather than one big correction.
Does the bracelet contain nickel, and can I wear it with a metal allergy?
The bracelet is nickel-free and made from solid, uncoated copper. If you have a known copper allergy, Wilson's disease, or broken skin, don't wear the bracelet. If you're unsure, talk to a doctor before wearing it for extended periods.
What's the difference between the four finishes?
Twisted has a classic, twisted cable structure with a finely braided pattern. Smooth puts the focus on an understated, unadorned surface and the warm copper colour. Hammered is hand-worked into a pronounced, handcrafted rhythm of facets. Round is the most understated finish: a thinner, round copper wire with a thick, ball-shaped knot at each end instead of a wide band. Material and quality are the same across all four.
Do I need to take the bracelet off to shower, swim or exercise?
Yes, take it off briefly for those. Chlorine, soap and sweat speed up discolouration on solid copper. Outside of those moments, you can just keep wearing the bracelet.
I see discolouration on my skin under the bracelet, is that harmful?
No, it's harmless. Copper reacts with moisture and salts in sweat to form a thin, greenish layer, which washes off with water and a cloth. It's a normal and temporary effect of wearing solid copper against the skin, and actually a sign of pure copper. If you want the bracelet shiny again, polish it with lemon and salt: how to do that is in the care guide.
Can the bracelet break if I adjust it often?
Repeatedly bending it wide open and closed can eventually cause metal fatigue and ultimately breakage, as with any piece of metal that's bent often. So adjust the size calmly and in small steps at the start, and avoid re-adjusting it again and again after that.
Not what you were after? No problem.
You have a 30-day right of return. Copper does take some getting used to: it tarnishes, it feels heavier in the hand than stainless steel, and now and then you will want to polish it. Give it a few weeks. If it is still not what you were after, send it back and get your money back.
