Buc-ee's Tumblers are stainless steel, double wall vacuum insulated. Keeps your drinks ice cold for longer - works great for hot beverages as well. The included shaded Splash Proof lid lets you know exactly how much drink you have. The flip-top closure resists spills and is straw- friendly. Easy to clean. This is a red tumbler featuring Bucky the Beaver. It holds 30 ounces.
