Parents, rejoice! These Contigo tumblers are the perfect solution when your little ones are ready to move beyond sippy cups but you're not ready for the mess. The 14oz size is just right for kids, and the magic is in the spill-proof valve inside the straw - these things won't leak even when upside down! There's also a silicone seal around the straw for extra protection against drips. The soft grip bottom pad helps prevent tipping on tables, and they fit perfectly in most car cup holders. Cleaning is a breeze since the straw twists apart and everything is top-rack dishwasher safe. They're 100% BPA-free and recommended for ages 3 and up. The bright patterns are fun for kids, and you get two in the pack so you always have a clean one ready. Seriously, these have saved so many car seats and living room carpets in our house! They're durable enough to handle being dropped (repeatedly) and the spill-proof feature actually works. Perfect for juice, water, or milk - your kids will feel like big kids drinking from 'real' cups, and you can relax knowing cleanup won't be a nightmare.
