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

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 12-ounce tumbler is vacuum insulated to keep drinks cold and stop condensation from leaving water rings. 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.

The silicone straw has a built-in valve that allows liquid to flow when drinking and prevents accidental spills when the tumbler is tipped over. The straw is also soft and comfortable for kids to drink from. Great for kids just graduating from sippy cups Can be disassembled for easy cleaning Silicone spout is soft and easy to drink from Double wall insulation keeps drinks cold for longer and prevents condensation 12 oz capacity Made of food-grade silicone and 18/8 stainless steel. Dishwasher safe, do not microwave Recommended for children ages 3 and up
