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

Review: Excellent cups, my daughter loves them! - Great quality, very durable, and the Disney Princess design is beautiful. They are the perfect size for toddlers' hands, spill-proof, and super easy to clean. Highly recommended!
Review: 🕷️ Perfect for Little Superheroes – Durable, Fun, and Truly Leak-Proof! - If you’ve got a toddler who loves Spider-Man and you’re tired of dealing with messy spills, the Zak Designs Marvel Kelso Toddler Cups are an absolute win. These cups are not only adorable and kid-approved, but also incredibly practical for everyday use—whether at home or on the go. We found these to be our best option due to our super active toddler who will throw it from time to time. Previous cups would start leaking over time but not these cups. They have held up to the abuse and still look like they just came out of the package. ✅ A Parent’s Dream: 🧃 Truly Leak-Proof: We’ve tested a lot of sippy cups over the years, and these are some of the most reliably leak-proof options we’ve found. They don’t drip when tipped, tossed, or even dropped—which makes them ideal for travel, car rides, or playtime chaos. 🕸️ Marvel Design = Instant Hit: The Spidey and His Amazing Friends graphics are vibrant, fun, and a huge hit with any superhero-loving toddler. They love picking their own cup and showing it off to friends. 💪 Built to Last: Made from thick, durable plastic, these cups hold up to toddler drops, dishwasher runs, and heavy use. They don’t crack or fade, and the lids fit securely without being impossible to remove for adults. 🙌 Easy to Use & Clean: The simple design means no extra valves or hard-to-scrub parts. They’re top-rack dishwasher safe and super easy to take apart and reassemble. 🎒 Great for On-the-Go: At 15oz, they’re the perfect size for keeping kids hydrated without being too bulky. They fit well in cup holders and diaper bags. ⚠️ A Few Quick Notes: Not Spill-Proof When Lid Is Off: This seems obvious, but just a reminder—once the lid is off, it’s a regular open cup. But with the lid secured, you’re good to go. Handwashing the Graphics May Prolong Life: We’ve put ours in the dishwasher plenty of times with no issues, but if you want to preserve the bright Spidey designs long-term, occasional handwashing may help. ⭐ Final Rating: 5 / 5 These Zak Spider-Man sippy cups combine fun and function in the best way possible. They’re durable, leak-proof, easy to clean, and your kid will absolutely love drinking from them. A must-have for any toddler who wants to drink like a superhero!

## 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.

### ⭐⭐⭐⭐⭐ Great toddler cups!
*by B***L on August 20, 2026*

We love these cups. They last for quite a long time. The kids love them and they are easy for them to hold. They are easy to clean and the seals hold up for a year at least. The patterns don’t wash off. They do have a tendency to leak out of the straw if left in a hot car. Pressure builds up and liquid comes out of the straw. You can buy replacement straws on Amazon! I highly recommend these cups for your toddlers.
