This fun straw tumbler will keep kids hydrated without any fuss! You can prevent messes and spills with a cup that won't leak: the attached 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 vacuum insulation will prevent condensation from forming on the outside of the cup, in addition to keeping drinks cold. Perfect for kids age 3 and up, this tumbler features colorful Ice Cream Pups artwork to make hydration fun.
