Highlights
Kelso Insulated Tumbler, 12 oz.
Ditch the spills, switch to zak!
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 kids can quench their thirst without the mess if it tips over. Perfect for car rides, park days, daycare, or home. It's the ideal choice for active kids or young ones just graduating from sippy cups. This Elmo Kelso tumbler is vacuum insulated to keep drinks cold for up to 10 hours and stop condensation from leaving water rings.
FAQs
Are these cups truly leak-proof?
A built-in straw valve prevents spills when tipped, shaken, or held upside down. However, a small amount may leak if a heavily filled cup is left lying on its side for an extended period. To ensure your Kelso tumbler stays leak-free, check out our quick care and assembly tips in this video.
Are these cups easy to clean?
The straw, spout, cup, and lid easily disassemble and can be tossed in the top rack of the dishwasher. However, avoid using straw brushes as they can damage the built-in valve. Hand washing the cup is recommended to preserve its design.
Are these cups safe for hot liquids?
No, these cups are designed for cold or room-temperature beverages only. They should not be used with hot liquids, and they are not safe for the microwave.
How long will it keep my child’s drink cold?
The tumbler is double-wall vacuum insulated and keeps drinks cold for up to 10 hours. It’s a customer favorite for maintaining temperature throughout the school day.
How easy is it to drink from the spout?
The bite-and-sip valve is intuitive for kids transitioning from traditional sippy cups to straw cups.
