Your kid wants to upgrade from a sippy cup and drink from a tumbler just like you, but you’re nervous about spills. With the Spill-Proof Kids Tumbler, you both win! A no-spill valve in the straw makes it impossible to spill, and a seal around the straw offers extra protection against leaks. A soft grip bottom pad helps prevent this brightly-patterned tumbler from tipping over on the dinner table, and it also fits most car cup holders, making it the perfect companion.
