This straw tumbler uses the buddy system to keep kids hydrated! A screw-on lid prevents splashes and spills, while a durable straw keeps water accessible. With fully wrapped art and the Frozen character Elsa sculpted in 360 degrees, this tumbler is fun from any angle. The hydration buddy is easy to keep close at hand; the tumbler fits in car cup holders and is small enough for kids to hold easily. Everything is made of durable plastic and completely BPA free. Hand washing is recommended, and the tumbler should not be microwaved. It’s recommended for children ages 3 and up.
