Kelso Insulated Tumbler, 12 oz.
Spaceships
- Built-in valve prevents leaks
- Detachable spout for easy cleaning
- Durable stainless steel
- Top rack dishwasher safe
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. This 12-ounce travel tumbler is vacuum insulated to keep drinks cold for up to 10 hours and stop condensation from leaving water rings. The stainless steel is durable, reusable, and completely BPA free, and shouldn't be microwaved. We recommend washing the tumbler by hand (to preserve the vacuum seal and keep the artwork bold and bright), but the lid can be disassembled and 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.
