This amazing Zircon Tumbler has a heavy-duty look, but it's made of lightweight aluminum for comfortable use and transport. The 16 oz. travel tumbler features a plastic inner liner, non-skid bottom, and double-wall construction for insulation of hot or cold beverages. It includes a screw-on, spill-resistant lid and matching 9" long straw. Add your custom one-color imprint to the front to create a personalized mug that's perfect for promoting your elementary school or as a teacher or staff appreciation gift or PTO/PTA fundraiser.
