Hiking mug

Description

Stainless steel on the inside and copper on the outside.
Normally, it is recommended to drink only water from copper mugs.
You can drink anything you like from this mug, as nothing comes out of the stainless steel inside.
But the outside still has an antibacterial surface.
Give up and absorb the heat and cold quickly.
Also suitable for hot drinks, but when tested it was found that the surface of the mug gets very hot, so hot drinks have to be drunk very carefully.
Still a suitable mug also for camping, as the liquid inside the mug warms up comfortably on the coals of the campfire.
