This tumbler uses the buddy system - Favorite characters make staying hydrated fun!This tumbler, with straw, lid, and sculpted character, keeps kids company and encourages a healthy intake of water throughout the day. It holds 15 ounces and is made of durable, long-lasting materials. The accordion straw is both flexible and tough against biting, and has a stopper to keep it from being pulled out and lost. The character graphic is fully wrapped and the figure on the lid is sculpted in 360 degrees, which means that it is visible from all angles. The tumbler is sized to be comfortable for small hands to hold, and it fits in most car cup holders for convenient travel. Everything is completely BPA free and top rack dishwasher safe. Do not microwave. Recommended for children ages 3 and up.
