This spill-proof Mighty Tot tumbler and bowl set from Zak Designs makes food and drink fun and easy! Durable Materials: The tumbler and bowl are made from lightweight plastic with silicone bases, and the comfortable straw is made from silicone as well. Everything is completely BPA free and dishwasher safe. Smartgrip Technology: The silicone bases provide suction when the cup and bowl are set on a smooth, flat surface, which prevents them from tipping over even when they're bumped. Both pieces are still easy to remove--just raise the tumbler straight up, and lift both levers on the bowl. The Mighty Mug & Smartgrip are used under license from Mighty Ventures, Inc. Leak-Resistant Lid: The tumbler lid screws on securely and has a straw with a built-in valve, which allows liquid to flow when drinking and prevents spills when the cup is turned upside-down. It's perfect for travel or for young children graduating from sippy cups. Hydrate Anywhere: The tumbler won't splash 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: 1 tumbler (10 oz capacity) and one bowl.
