    • Adorable, Durable, and Truly Leak-Proof
Color: Underwater Size: 15oz Style: Drinkware
This Zak Designs Kelso tumbler set is perfect for kids! The underwater theme is super cute and my little one loves the fun design. The 15 oz size is just right—not too big, not too small—and the screw-on lid with straw is completely leak-proof, even when tipped over or dropped. The plastic and silicone are sturdy and easy to clean, and the whole set holds up really well to daily use. Great for home, daycare, or on the go. I’m so impressed with the quality and design—definitely a 5-star buy! ... show more

    • Great Cups!
Color: Paw Patrol - Chase & Marshall Size: 15oz Style: Drinkware
Purchased these to help with moving my toddler from a sippy cup towards a regular cup. These work great and I have purchased Mutiple different characters for her which she loves, and she gets to choose which one she wants to use. These are easy to clean, stand up in the dishwasher, and do not get damaged or warped. Ice stays good in them, the colors are bright and beautiful, water retention is good with no leaks, and a good value for the money. ... show more

    • Great leak proof cups
Color: DinoRoar & Zaksaurus Size: 15oz Style: Drinkware

Love these cups since they don’t leak even with my son tossing them around. They only leak if you bend the straw, but otherwise they work well. Great quality and we own three sets in fun designs.

    • Favorite cups!
Color: Disney Moana 2 Size: 15oz Style: Drinkware
This is the thirs set of Zak cups we have purchased and we love them. They do not leak unless you punch the straw at the level of the valve and trip the cup- an action that is not going to happen often with young toddlers. I will say our older, more used/washed plastic kelso Zak cups definitely show the wear and tear as the characters on the cup have been slowly chipping away with how often they get washed (mostly hand washed to be quickly re-used). Cute bright colors. Easy to clean as all parts come apart. ... show more

    • Nice, Functional
Color: Unicorn Size: 15oz Style: Drinkware
These are so easy to clean and cute. Warning though: they are NOT leakproof. They are resistant to leaks, but toddlers can definitely use them to make a mess.

    • 🕷️ Perfect for Little Superheroes – Durable, Fun, and Truly Leak-Proof!
Color: Spidey and His Amazing Friends Size: 15oz Style: Drinkware
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! ... show more

    • Overall good product
Color: Dr. Seuss (One Fish Two Fish) Size: 15oz Style: Drinkware
Love the designs. In the very beginning there were no leaks from the straw but after 6 months of use the straws now leak. They are a little large for my 19month old but he still uses them. They fit perfectly in our carseat cupholder. I would buy again because overall it's a good product.
