Insulated Stainless Steel

Sip on through to the other side with the brand new straw tumbler that’ll never slip, thanks to a non-slip silicone pad on the base that grips surfaces to avoid scratches and spills. The strong and durable 20 oz Straw Tumbler is constructed in double-walled, vacuum-insulated stainless steel with a powder coat finish, keeping it looking good on the outside and at piping hot on the inside. Dishwasher safe and free of BPA, BPS, and BPF.
