These 20 oz tumblers are made to order. All of our tumblers are stainless steel insulated and feature double-wall, vacuum insulation with a clear slide lid, rubber bottom disk and a stainless steel straw! They are 2x heat and cold resistant compared to glass or plastic. Each tumbler is BPA and lead free!
The tumbler itself is hand wash only, the other items are able to be washed in the dishwasher. Failure to wash correctly could result in a lower lifespan of the design.
