Be ready to drink your favorite beverage anywhere you go in the compact-sized ceramisteel-made everyday tumbler. This compact tumbler can hold up to 12 oz. of your choice of drink. Each tumbler is BPA-free and has an outer and inner that is made of stainless steel with an inner ceramic coating which will remove the metal-like taste and keep your drink's natural flavor. Plus, the ceramic inner coating will also protect this tumbler's stainless steel from being tainted. Keep your drinks cold or hot for longer periods of time as this FDA-approved tumbler is vacuum insulated and is constructed with double walls. Drinking from this bottle is also easy as it sports a spill-resistant snap-on lid that opens by thumb sliding. Make sure to wash this tumbler by hand washing it after every use.
