Yes. CopperWater bottles are pure copper on the inside, with no lining, no coating, and no other metals. They are solid copper through and through at 99.95% and above purity. The inside must be bare, uncoated copper for the health benefits to work, because the copper needs to be in direct contact with the water.
Why the inside has to be uncoated copper
The benefits of a copper vessel come from copper interacting directly with the water it holds. If the inside were lined or coated with lacquer or another metal, the water would never touch the copper and the bottle would offer nothing that a normal steel bottle does not. That is why a genuine Ayurvedic copper bottle is bare copper inside.
How we verify it
CopperWater bottles are solid copper inside and out, verified through regular third-party testing by SGS. You can see photos of the bare copper interior on our product pages, and our published lab results confirm the purity.
