Nickel-free and uncoated, so the metal can react directly with air, moisture and skin contact.
Twisted, smooth, hammered or round: the same copper quality, each with a different texture and look.
In the oldest clinical study (Walker and Keats, 1976), copper bracelets released an average of 13 milligrams of copper per month through the skin.
You slide the bracelet over your wrist instead of clasping it shut. Bend the ends carefully and as little as possible when adjusting it.
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 (not too hard: salt is mildly abrasive and dissolves well in the lemon juice). Exactly how is in the care guide.
The material is analysed by RTC Laboratory in Moradabad, a NABL-accredited lab, tested to ASTM-1621 and IS-228. In the sample that was analysed the measurement came out at 99.21% copper and 0.75% zinc; the remaining 0.04% falls within the measuring range of the analysis. Food safety is covered by a second report, from URS Products and Testing: tested against EC 1935/2004 and REACH, using the heavy metal limits from EU 10/2011 as the benchmark.
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.
Take the bracelet off when you shower, swim and exercise. Soap, chlorine and sweat make the copper darken faster; keep it dry and the shine holds far longer.
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.
More has been measured about copper on the skin than most people realise: the oldest clinical bracelet study measured an average release of 13 milligrams of copper per month, the dermatologists Hostynek and Maibach showed that metallic copper passes through the outermost layer of skin, and in wound care copper dressings sped up healing. What may officially be said about copper in the EU, and what that rests on, is set out in the eight official EU claims.
Your body makes a copper compound of its own too: GHK-Cu, a tripeptide that holds on to copper. At twenty there are around 200 nanograms per millilitre of it in your plasma, at sixty still 80, and research describes it as stimulating collagen and elastin. Wound dressings with copper oxide have meanwhile been cleared by the American FDA and have been in medical use for over six years. What all of that does and does not say about a bracelet is in copper on your skin.
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.
This way you start with an even shine and see the patina develop from the beginning.
Slowly bend the ends a little open or closed with both hands. Do this as little as possible: copper only tolerates limited bending.
Turn the opening towards the inside of your wrist, slide the bracelet over and turn it back. It should stay on without pinching.
Take it off for swimming, showering, sport and cleaning. Chlorine, soap and sweat speed up tarnish.
Copper reacts with sweat to form a thin greenish film. Harmless: rinse and wipe it off.
For shine: polish with lemon and salt (not too hard: salt is mildly abrasive and dissolves well in the lemon juice) and dry right away. For dark patina: do nothing. Keep it in the velvet pouch.
The packaging also carries a QR code that takes you straight to this guide.
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.
In the velvet pouch you keep it safe and take it along.
You unpack a luxury black jewellery box. So you can give it away straight from the box, without wrapping anything around it.
A Kopero card is inside the box. The QR code on it takes you to the digital manual.

Unlike a closed ring, the open bangle simply slides around your wrist. You quickly forget you're wearing it, even though you can still feel the twisted texture.
Twisted, smooth, hammered or round: always the same open bracelet in solid copper, only the surface differs. Here you see them together.
Unpack it at your own pace, feel the weight and see whether the size suits you. If it is not for you, send it back within thirty days and get your money back. If you use it for longer than you need to judge it, we may deduct for loss of value. You arrange the return yourself with whichever carrier suits you best, or you ask us for a return label. The cost of sending it back is yours.

I have a nickel allergy and have already bought three bracelets labelled ‘100% copper’ that gave me a rash within half an hour. I've now been wearing this bracelet for four days and am completely happy with it. It's always nice when a seller is honest. Arrived quickly. Nicely packaged. A lovely, substantial bracelet that can be adjusted to fit. This is the bracelet I should have bought straight away.
It looks lovely. The quality is good too: solid, yet bendable (in other words, adjustable to fit). So, once again, very happy with it.
I ordered this bracelet because I think it's beautiful and because it is said to have healing properties. Even in the Bible, the Israelites had to look at the copper serpent erected in the desert for healing. I haven't worn it long enough to tell whether it helps with painful joints. Perhaps that will come. I'm curious. In any case, I think it's a lovely piece of jewellery.
A very beautiful copper bracelet that can be worn by both men and women! It looks a little more understated than the twisted version; I actually bought both, and the recipient was very happy with them!
Really beautiful, genuine copper, so exactly as described!
A very beautiful, luxurious bracelet that fits very comfortably and is easy to adjust.
Lovely bracelet, a good website and careful delivery.
Lovely bracelet and dispatched quickly. It fits well even on my slim wrist.
Good quality
Very beautiful, happy with it.
Fine, it looks good too.
Beautiful, simple copper bracelet, easy to adjust to size and delivered perfectly with storage and information.
Lovely bracelet with clear cleaning instructions.
A beautiful, sturdy bracelet. It came with a lovely box and pouch. 5 stars!
Even more beautiful in person!
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.
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.
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.
Take it off for those. Soap, chlorine and sweat make the copper colour up faster; keep it dry and the shine stays far longer. Outside of those moments, you can just keep wearing the bracelet.
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 (not too hard: salt is mildly abrasive and dissolves well in the lemon juice): how to do that is in the care guide.
Adjust the size calmly and in small steps at the start, and it will sit right afterwards without you having to pull at it again. Like any metal, copper tires from being bent wide open and closed repeatedly, so the less you adjust it, the longer it lasts.
