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
We kept getting little flies around an indoor planter. Since the antenna went in there are noticeably fewer. No idea why, but it's welcome.
Translated from Dutch
Sleek and timeless design, exactly my taste.
Translated from Dutch
In Ayurveda I read that water is kept in copper for several hours. I now do that every evening and find the taste genuinely much nicer.
Translated from Dutch
I leave the water for about eight hours. The taste turns calm and clean, with no clear metallic note.
Translated from Dutch
400 ml of copper water in the morning and I'm awake. No fireworks, but a clearer feeling that lasts longer.
Translated from Dutch
During a sound session the pyramid stood in the middle. The energy felt focused and everyone stayed remarkably quiet afterwards.
Translated from Dutch
Powerful and still calm to look at. After a busy working day I sit beside it for ten minutes and feel the tension drop.
Translated from Dutch
I use it as a focus point in my hand while meditating. The copper warms up and gives me a solid, grounded feeling. At first it lay unused in a drawer for a week. When I put it back next to my bottle the taste difference stood out again. Now it even comes with me to the office.
Translated from Dutch
I taste toothpaste for less time after brushing and food tastes more normal. Clearly a lot of coating used to stay behind. One weekend I skipped it once. I immediately missed that clean feeling. Since then the scraper simply travels with me in its pouch.
Translated from Dutch
In Ayurveda copper water is often drunk in the morning. Now I get the appeal: it tastes mild and the moment itself calms me.
Translated from Dutch
The potatoes stand stronger and the foliage stays fresh longer. Wow, I wish I'd tried this sooner.
Translated from Dutch
Bent it gently to size once, and it has fitted perfectly ever since.
Translated from Dutch
The hammered surface sits firmly in the hand. Oddly enough the water also seems to stay cool longer, though I haven't measured it.
Translated from Dutch
With the lid on, the water seems to stay fresher. I fill it around ten in the evening and pour at six.
Translated from Dutch
No acidic drinks in it, I stick to that properly. With plain tea and water I taste a soft, clean flavour.
Translated from Dutch
The small pyramid helps me focus during breathwork. My thoughts scatter less and I settle down faster.
Translated from Dutch
On my desk it helps against that hurried feeling after a lot of video calls. A quick look at the shape and I'm back with it.
Translated from Dutch
No power, no noise, nothing. And still our hard tap water tastes less hard to me. Fairly remarkable.
Translated from Dutch
The scraper leaves no metallic taste. After rinsing, my tongue feels clean and fresh.
Translated from Dutch
Wow, even at room temperature I experience the water as lovely and fresh. A pleasure to taste.
Translated from Dutch
The 30 cm size disappears nicely among my herbs, and the four spirals were in place within minutes.
Translated from Dutch
Wow, within a week my wrist felt more supple during yoga. The bracelet doesn't get in the way during the poses either.
Translated from Dutch
The smooth rim is pleasant to drink from, and 300 ml is a good amount for my morning.
Translated from Dutch
At 1.4 litres there's enough water ready in one go for our whole breakfast.
Translated from Dutch
The 400 ml capacity is wonderfully generous for tea or a large glass of water.
Translated from Dutch
Wow, the large one really has presence. My meditation spot feels stronger and I sit for longer without fidgeting.
Translated from Dutch
The large pyramid changed the atmosphere in my treatment room. People start speaking more quietly of their own accord. I've noticed it too often now to ignore it.
Translated from Dutch
I sometimes put my keys and bracelet inside it. The bracelet especially feels warmer and stronger afterwards when I put it on.
Translated from Dutch
No more gagging like with a plastic scraper. The wide arc covers the tongue in two or three strokes.
Translated from Dutch
The slim shape sits comfortably in the hand and 900 ml is a good amount for the morning.
Translated from Dutch
I have two rows of beans side by side. Only one row has the copper spirals. Those plants are taller and greener. To me the difference is very clear.
Translated from Dutch
My skin feels calm under the bracelet and the copper warms up pleasantly fast. Very comfortable.
Translated from Dutch
My daughter said out of the blue that the water was 'nicer'. She didn't even know I'd used a different cup.
Translated from Dutch
Our limescale-heavy water suddenly feels much softer in the mouth. It's genuinely pleasant to drink.
Translated from Dutch
Black coffee is still coffee, of course, but I taste it more intensely and less watery. A surprisingly big difference.
Translated from Dutch
On a low cabinet the shape gets plenty of room and really comes into its own.
Translated from Dutch
An impressive object for the home that stays light thanks to its open form.
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
My daughter keeps taking my 'nice water' because she thinks it tastes better. By now I have to hide the bottle if I want any myself.
Translated from Dutch
Exactly the length I needed.
Translated from Dutch
Comfortable and subtle, I wear it day and night.
Translated from Dutch
The hammered effect makes it truly unique.
Translated from Dutch
Gorgeous piece, also very decorative.
Translated from Dutch
Gorgeous pattern, a real showpiece on the table.
Translated from Dutch
I write an intention on a small piece of paper and put it underneath. It helps me stay with it through the day instead of forgetting it straight away.
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.
