This Eco-friendly Plant Based Travel Mug not only looks good, but it's a piece of drinkware you can feel good about, too. The 7" high, 20 oz. (18 oz. with lid on) travel tumbler is made with BPA-free plastic and small amounts of plant-based material to create a flecked finish. It is double-wall constructed for the insulation of hot or cold liquids and includes a snap-on, spill-resistant lid with rubber gasket to keep beverages secure. Customize the tumbler with your choice of one-color imprint to create a one-of-a-kind "green" keepsake to match a garden Prom or Homecoming dance theme or Senior Party. Note: Testing showed no indication of extractable gluten in this tumbler.
