Highlights
Kelso Tumbler, 15 oz. (2 Pack)
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 it's perfect for the car, park days, daycare, or home—wherever your little one goes. Easy for children to quench their thirst but won't make a mess if tipped over. The Kelso DinoRoar and Zaksaurus tumbler is the perfect choice for active kids, or young ones just graduating from sippy cups who aren't ready for an open-topped tumbler yet.
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.
Can my child pull the straw out of the lid?
No, the straw is designed so that it cannot be pulled out from the top by a child, which helps prevent spills and lost parts.
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.
