Drinks stay hot or cold: our double-walled, vacuum insulated stainless steel mugs come with an open port lid and will keep your drinks the temperature you want! The standard lids contain a straw friendly open port drinking hole. Engraving is permanent, but it is not recommended for dishwasher use. We do not use vinyl, decals, or wraps on our mugs! Each is powdercoated for extreme durability!
