Woodcraft 15oz Shop Mug Insulated Stainless Steel
Double wall, stainless steel shop mug. Nothing fancy like drink spouts or nonslip bottoms or anti-spill lids. Just a great mug that keeps cold drinks, cold and hot drinks, hot - not forever but long enough and you don't have to worry about breaking it. We won't say it's unbreakable, but it would take a fair amount of abuse to make it leak.
