What pure copper does for you
Copper has been used for thousands of years to drink from, to wear and to care for the body. Research now confirms why: the metal is naturally antibacterial, an essential mineral for your body, and it measurably changes the water it touches.
-
Kills bacteria on contact
In laboratory tests, cleaned copper killed more than 99.9% of bacteria such as MRSA and E. coli within two hours.
EPA registration, 2008 -
Changes the water it touches
In one study, water kept in a copper vessel for sixteen hours was completely free of bacteria and had a measurably higher pH.
Sudha et al., 2012 -
A mineral your body needs
Copper is an essential trace element, involved in your energy metabolism and the protection of your cells.
Nutritional science -
Copper works with your skin
Your body makes GHK-Cu itself, a tripeptide that holds on to copper and stimulates collagen and elastin. Wound dressings with copper oxide are cleared by the US FDA and have been in medical use for over six years.
FDA-cleared wound dressing -
Lasts a lifetime, and then another
Copper loses none of its properties when it is melted down. Most of the copper ever mined is still in use somewhere.

Reviews from across the shop
Nice finish, easy to place in the garden.
Translated from Dutch
I wear it every day, it's comfortable and looks stylish.
Translated from Dutch
Since I put one next to my pepper plant, it finally seems to have woken up. New shoots, a sturdier stem. Could be coincidence, but I'm certainly not taking it out again.
Translated from Dutch
I'd read that copper is traditionally worn for supple joints. My hand feels looser, and that's a really good experience for me.
Translated from Dutch
I bought this because of Ayurveda and tamra jal. I enjoy the morning ritual, but it was mainly the rounder taste that surprised me.
Translated from Dutch
Wow, that typical swimming-pool smell of our tap water is almost gone. That alone makes the jug worth it for me.
Translated from Dutch
I use it during my morning meditation. Warm water in it, hands around the handle, and I arrive faster. A powerful feeling.
Translated from Dutch
My bedroom feels less busy since it's been there. Maybe it's the shape, maybe the copper, but the calm is welcome. Before, the stones just lay loose on the bedside table. Now it feels like I close the day deliberately when I put them under the pyramid. That small ritual brings a surprising amount of calm.
Translated from Dutch
An hour with my crystals underneath and they feel cool and clear. Genuinely wow for such an understated object. I deliberately compared over several evenings. With the pyramid I found my calm faster every time. It has had a fixed spot ever since.
Translated from Dutch
I use the ring loose next to the water jug. That works very easily and the water feels distinctly rounder in the mouth.
Translated from Dutch
I often had a thick white coating on my tongue when I got up. After two weeks of daily scraping that has reduced a lot.
Translated from Dutch
Coming from Ayurveda I wanted to keep water in copper overnight. After a week I noticed my stomach starts the day calmer and I reach for coffee less quickly.
Translated from Dutch
My tomatoes have grown ridiculously well this year. The plants stand sturdier and I already have more flower trusses than around this time last year.
Translated from Dutch
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.
Translated from Dutch
Wow, water really does taste fresher from this. My ordinary glass next to it suddenly tasted dull.
Translated from Dutch
After a night the water tastes noticeably mild. My first reaction was genuinely: wow, why can I taste this difference so clearly?
Translated from Dutch
Wow, my morning tea suddenly tastes much fuller. I use no lemon or milk, so the flavour really comes through.
Translated from Dutch
The twisted ribs catch the daylight beautifully and draw the eye up to the apex.
Translated from Dutch
The smooth lines look calm and go beautifully with wood and pale stone.
Translated from Dutch
Slid it over the tap and tasted it the same evening. The water tastes softer, less sharp. Very curious.
Translated from Dutch
After a single use far more coating came off than with my toothbrush. My mouth felt fresher straight away. Wow.
Translated from Dutch
The water from this bottle really does taste different. Softer, fresher and without that tap smell. I'm sold.
Translated from Dutch
After a few strong gusts all four were still standing perfectly upright.
Translated from Dutch
Lovely gift packaging, and the bracelet looked even better in real life than in the photo.
Translated from Dutch
Together with the copper jug it makes a lovely set on the table.
Translated from Dutch
On the table it draws attention straight away and we often get nice questions about it.
Translated from Dutch
Every fall of light looks different on the hammered copper.
Translated from Dutch
I put my bracelet under it when I'm not wearing it. Afterwards the copper feels fresh and warm again when I put it on.
Translated from Dutch
My copper bracelet goes under it in the evening. In the morning it feels stronger to me again, as if the charge is back.
Translated from Dutch
The velvet pouch is handy when I want to take the ring along with a bottle.
Translated from Dutch
The velvet pouch makes it easy to take along when travelling.
Translated from Dutch
The patina deepens the relief and keeps getting more beautiful.
Translated from Dutch
My rosemary did almost nothing for months. Now fresh tips are coming through everywhere. Just wow.
Translated from Dutch
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.
Translated from Dutch
My stomach feels calmer since I drink this water first thing in the morning. That's my own experience, of course, not a medical claim.
Translated from Dutch
With lukewarm water I taste the difference most strongly. It feels almost silky. Yes, that sounds over the top, but that's how I experience it.
Translated from Dutch
Since drinking from this I take more deliberate sips. Sounds like a small thing, but I drink less hurriedly and feel better afterwards.
Translated from Dutch
The large size leaves room for a glass, stones and a personal note all at once.
Translated from Dutch
The wide base gives plenty of freedom to arrange things differently each time.
Translated from Dutch
The solid copper feels sturdy and the circle is cleanly finished.
Translated from Dutch
Rinsing it is quick and then it hangs on a hook to dry.
Translated from Dutch
Powerful morning ritual: fill, sleep, drink. Simple, but my energy feels steadier right up to lunch.
Translated from Dutch
My neighbour asked what I had stuck in the soil. A month later he asked again, but that time because the sunflowers were so tall. That says enough for me.
Translated from Dutch
The texture hides marks of use nicely and gives the bracelet a rugged look.
Translated from Dutch
Hard to explain until you taste it. Water doesn't turn sweet, but it does turn softer. A really nice discovery.
Translated from Dutch
Since the jug has been standing there we empty it every morning. That never worked with a glass carafe. Maybe the ritual is half the power.
Translated from Dutch
After a week I noticed I was having my morning coffee later. Warm copper water first simply feels better in my body.
Translated from Dutch
At first I mainly bought it because I liked the look. Then I put a glass of water underneath and it tasted noticeably soft the next day. Now I do that every evening.
Translated from Dutch
Copper deserves a place in your day again
For centuries copper was a matter of course in drinkware, jewellery, care rituals and gardens. We are bringing that versatility back in products you can genuinely use.
Kopero does not choose between measurable material knowledge and older or energetic traditions. It is precisely the combination that makes copper so fascinating, and it leaves everyone room to find a ritual of their own.

Frequently asked questions
Does copper discolour over time?
Yes, and that's normal. Uncoated copper reacts to air, water and touch, developing a brown to dark surface patina. That's not a defect but a sign of real, solid copper. Want the original shine back? Simply polish it up; leave the patina alone and it will deepen naturally over time.
More on this: why copper turns green or black
Have your products been tested?
Yes, by two independent laboratories. RTC Laboratory in Moradabad measured the composition and arrived at 99.21% copper and 0.75% zinc, to ASTM-1621 and IS-228. URS Products and Testing in Noida put a water bottle, a mug and a pyramid against the European rules for materials in contact with food: overall migration, odour and taste, nineteen heavy metals, and lead and cadmium in the material itself. Everything passed, and not one of those nineteen metals was detectable in the water that had been standing in the product.
More on this: what our copper is made of
What should I keep in mind with a copper bottle?
Three things, and we would rather name them up front. You wash a copper bottle by hand, not in the dishwasher. It takes on its own patina over the months, precisely because there is no coating over it to prevent that. And still water is what goes in: lemon water, anything carbonated and sports drinks are acidic enough to dissolve copper faster. That is exactly the difference from a coated bottle: here you drink from the solid metal itself, and with normal use that lasts for years.
