Zak Designs 12oz Kids Straw Tumbler, Stainless Steel Vacuum Insulated Kincaid Tumbler with Silicone Straw Utilizing Leak-Proof Valve, Travel Straw Tumbler, Disney Princess

Let's keep it simple: this tumbler doesn't leak. The silicone sipper spout has a built-in valve that stops water from flowing when no one is drinking, so it's easy for children to quench their thirst but won't make a mess if the tumbler is tipped over. It's the perfect choice for active kids, or young ones just graduating from sippy cups who aren't ready for an open-topped tumbler yet. The stainless steel is durable, reusable, and shouldn't be microwaved. We recommend washing the tumbler by hand (to preserve the vacuum seal and keep the artwork bold and bright), but the lid can be disassembled and put in the top rack of the dishwasher for a quick and easy clean.
