Does the Kelso prevent spills when the tumbler is tipped over?
Yes, and you don’t need to remember to close the lid! The Kelso tumbler has a valve in the spout, which lets water flow freely when kids are drinking, but stops spills if the tumbler is tipped over.
Is the tumbler easy to clean?
Yes, both the spout on top of the lid and the inner straw underneath the lid are removable to make cleaning easy, and the parts are all dishwasher safe.
How old should my child be to use the Kelso tumbler?
We recommend this tumbler for kids age 3 and up.
What kind of drinks can go in the Kelso tumbler?
The Kelso tumbler is perfect for everyday cold beverages like water, milk, or juice. Thick smoothies are a little more difficult to drink with the valve, while carbonated drinks can build pressure and push liquid up through the straw.
Can I travel with the Kelso?
The Kelso tumbler fits in most car and stroller cup holders for on the go convenience. We don’t recommend putting the Kelso tumbler in a bag, as pressing on the soft spout can open the valve and allow drinks to flow out.
SIZE: The set contains two different Bluey tumblers that are 3.20 inches in diameter and 6.67 inches tall. They have a capacity of 15 ounces.
MATERIAL: The durable tumblers are made of plastic with silicone straws. They’re dishwasher safe, can be disassembled for easy cleaning, and should not be microwaved.
LEAK-PROOF DESIGN: The silicone straw has a built-in valve that allows liquid to flow when drinking and prevents accidental spills when the tumbler is tipped over. The straw is also soft and comfortable for kids to drink from.
AT HOME OR ON THE GO: The straw tumbler is suited for travel, since it won’t leak and fits in car cup holders while keeping drinks easily accessible. It’s also great for drinking beverages at home without worrying about stains or nearby electronics.
LIFESTYLE: Zak Designs drinkware makes hydration fun! These tumblers are a great gift for kids just graduating from sippy cups. The tumblers are fully reusable–no more disposable cups–and a fun addition to the daily routine.
