The Welly® Copper Vacuum Insulated Bottle features durable, double-wall stainless steel vacuum construction with copper insulation, which allows your beverage to stay cold for 48 hours and hot for at least 12 hours. The construction also prevents condensation on the outside of the bottle. Removable stainless steel infuser included. Comes complete with on-trend, durable powder coating and the natural bamboo wrap. It features a screw-on lid and a wide opening for comfortable filling and pouring. Perfect for ice cubes and fits most standard car cup holders. Due to the nature of bamboo and powder coated materials, there might be a slight difference on laser engraved logos. No two pieces are alike which makes each piece unique for you!
