This leak-proof tumbler from Zak Designs makes hydration fun for any Disney fan! Durable Materials: The tumbler is made from food-grade, 18/8 stainless steel, and the comfortable straw is made from silicone. Everything is completely BPA free, and the lid can be disassembled for easy cleaning. Leak-Proof Straw: The straw spout has a built-in valve that allows liquid to flow when drinking and prevents spills when the tumbler is tipped over. It's perfect for travel or for young children graduating from sippy cups. Vacuum Insulation: The stainless steel tumbler has vacuum insulation that keeps drinks cold for up to 10 hours, so your water is always refreshingly chilled. The double-wall construction also prevents condensation from forming on the outer walls, eliminating messy water rings.Hydrate Anywhere: The tumbler won't splash or leak and fits in car cup holders, making it ideal to take on the go. At home, you don't have to worry about spills or stains around fabrics or electronics, and drinks stay easily accessible through the straw. Specifications: 12 oz capacity. Vacuum insulated.
