## Description

desertcart.com: Zak Designs Kelso Tumbler Set 15 oz, (Unicorn) Leak-Proof Screw-On Lid with Straw Made of Durable Plastic and Silicone, Perfect Cup Bundle for Kids (2pc Set) : Baby

Review: Good cup for toddlers - The cups themselves do a good job of not leaking for the most part but if they get dropped a lot the lid doesn’t quite line up properly so it will slightly leak. The cup also comes apart to make it easier to clean, you will need a little cleaning brush to clean the silicone straw that has a few spots that I’ve noticed start to grow mold but it’s easy to clean when a small straw cleaner brush. The cup is a great size for my toddler to hold and the cup itself hold a good amount of water. The paint/design does not hold up very well, I’ve hand washed as well as used the dishwasher and both cause the design to start coming off.
Review: Awesome no spill straw cups - These cups are awesome. Great to teach your kiddo how to use straws. The straw has a little flap in it to prevent spills as well. You can also remove the plastic straw part that’s inside the cup if your baby keeps tipping the cup upwards as well so it’s nice that it’s functional that way too. The designs are adorable and these are easy to clean.

## Features

- SIZE: The set contains two tumblers that are 3.16 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 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 colorful 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.

## Questions & Answers

**Q: Does the Kelso prevent spills when the tumbler is tipped over?**
A: 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.

**Q: Is the tumbler easy to clean?**
A: 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.

**Q: How old should my child be to use the Kelso tumbler?**
A: We recommend this tumbler for kids age 3 and up.

**Q: What kind of drinks can go in the Kelso tumbler?**
A: 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.

**Q: Can I travel with the Kelso?**
A: 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.

### ⭐⭐⭐⭐⭐ Easy to clean
*by A***E on December 29, 2025*

Best cup I’ve found. Leak proof and extremely easy to clean. This is used daily. I run them through the dishwasher. The pattern/design fades over time but the functionality remains so it’s not a big deal for me. I use 3rd party replacement spouts when the leak proof flaps inside rip.
