Kelso 3 Piece Tumbler Set
Campout / Stainless Steel and Plastic
Leak-Proof
Vacuum Insulated
Soft Straw
Cup Holder Friendly
Let's keep it simple: these Campout tumblers don't leak. The silicone sipper spout design has a built-in valve that stops water from flowing when no one is drinking: 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. Two tumblers and a bonus sipper are included in the set—the 12-ounce stainless steel tumbler has vacuum insulation, which keeps drinks cold and eliminates water rings from condensation, and the 15-ounce plastic tumbler is lightweight and easy to carry. They're both durable, reusable, and completely BPA free.

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.
