The 1200 ml Topazima 1200ml Stainless Steel 1200 Ml Tumbler. Tumbler is made of recycled stainless steel, making this tumbler a more sustainable choice. The advanced FlowState lid features a rotating cover with three positions: a straw opening designed to resist splashes while holding the reusable straw in place, a drink opening, and a full cover top. Thanks to the vacuum insulation, the beverage will stay cold for 11 hours (48 hours when iced). The ergonomic handle has comfort grip inserts for easy carrying, and the narrow base fits most car cup holders.
