Kelso Tumbler, 15 oz. (2 Pack)
Baby Shark
Leak-Proof
Soft Straw
Cup Holder Friendly
Let's keep it simple: this tumbler doesn't leak. The silicone sipper spout has a built-in valve that stops water from flowing when no one is drinking, so it's easy for children to quench their thirst but won't make a mess if the tumbler is tipped over. It's the perfect choice for active kids, or young ones just graduating from sippy cups who aren't ready for an open-topped tumbler yet. The 15-ounce tumbler is made of durable plastic, which is lightweight, sturdy enough for everyday adventures, and completely BPA free. We don't recommend putting it in the microwave—this cup is made for cold drinks—but the lid can be disassembled and everything can be put in the top rack of the dishwasher for a quick and easy clean.

Questions & Answers
The silicone sipper spout has a built-in valve that stops water from flowing when no one is drinking. To securely close the screw-on lid, place it on top of the bottle and rotate it clockwise until it stops turning. Make sure that the lid stays level as it moves and check to see that it is not sitting crookedly on top of the bottle.
Kelso tumblers are top rack dishwasher safe! To avoid residue build-up, do not leave beverages in the bottle for long periods of time (overnight) and allow pieces to fully dry when washed. To ensure the artwork remains vibrant, we recommend hand washing when possible. Also, the spout is detachable for easy cleaning.
