This fun straw tumbler set will keep kids hydrated without any fuss! You can prevent messes and spills with a cup that won't leak: the comfortable silicone straw has a valve that allows easy access to water, but won't drip when the tumbler is tipped over. A screw-on lid means a secure fit, and when it's time to clean up, the lid is easy to disassemble and everything is dishwasher safe. Perfect for kids age 3 and up, this tumbler features Bluey artwork to make hydration fun.
