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 a laboratory study, the tested bacteria could no longer be cultured after 16 hours, and pH rose slightly. Those 16 hours were the study duration; the evening-to-morning ritual is about 8 hours.
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.

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. Solid 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% (RTC 2021) 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.
RTC (2021): 99.21% copper and 0.75% zinc. URS (21 October 2026), a separate bottle sample: 99.18% copper and 0.498% zinc.

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. And still water is what goes in: lemon water, anything carbonated and sports drinks are acidic enough to dissolve copper faster. The inside is bare copper. With normal use and care, the bottle lasts for years.
