Did you guys know you can powder coat stainless steel? This means you can get whatever stainless steel mug you want then be as artistic as you want to draw whatever on it with the powder coat then put it in an electric oven to finish it. Just use food grade powder coat.
Just wear PPE, unlike this moron and don't use these yeti shits,
