Sigg Gemstone
Question about Sigg Gemstone
Is steel coated on the inside (with food contact)? The description (website) says something about copper, but I'm not sure if this applies to the intermediate wall or the inside.
"The bottle is a double-walled insulated stainless steel drinking bottle." = inside and outside wall made of stainless steel.
"The Gemstone collection contains a copper coating in the bottle, which guarantees the best possible insulating effect" = in the middle, between the stainless steel, a copper coating.
