This 12 oz. Short Stainless Steel Mason Tumbler combines two popular drinkware styles in one! The square design of a mason jar is paired with a stainless steel exterior and plastic inner liner. The double wall construction properly insulates* your hot or cold beverages. The tumbler also features a screw on, spill-resistant thumb-slide lid. Customize the Tumbler by adding your choice of a one-color pad-printed imprint on one side. Add any kind of design you want--motivational message, school name and/or mascot, recognition award verbiage, or school event like Prom, Homecoming, or Senior Party. Measuring 4 1/2" high, this tumbler meets FDA requirements and is BPA free; hand washing is recommended. *NOTE: Due to the vacuum insulation technology, capacity is 10 oz. with the lid on.
