These mugs are great for cold drinks. The copper is shiny and my drinks stay cold for hours! I only hand wash them to keep them looking new and I always dry them immediately so they don't get spots. What I like best is the capacity. They don't look big, but they hold a lot of fluid! They will easily accomodate a can of soda with plenty of room for ice. (Careful when using them for "adult beverages", because the size is deceiving. They arrived in a nice, giftable box, but I kept them for myself! Living in SW Florida, any cup that keeps my drinks cold like these do doesn't get given away! These stylish cups would be perfect for a housewarming gift or to use at your home bar. #rankboosterreviews #sponsered #deik #moscowmule #coppermugs
