absolutely love these cups for my toddler. spill proof, cute & easy to clean. they’re durable & good quality, they’ve quickly become to only cups we like to give our 2 year old.

I absolutely love these Zak Designs Disney SuperKitties Kelso toddler tumblers! The colors are bright and fun, and the SuperKitties designs are adorable — my little one was instantly obsessed. The size is perfect (15 oz), and I love that they come in a 2-pack so we always have a clean one ready to go. The best part? They really are leak-proof. I’ve tossed them in a diaper bag and they haven’t spilled once. The straw is soft and easy for toddlers to drink from, and the cups feel sturdy and durable — not flimsy at all. They’re great for home, car rides, and on-the-go. Easy to clean and hold up well after multiple washes. Definitely worth it and I would 100% buy them again!

I’m not kidding- these are the only cups my toddler will use and I have gone through dozens of others. He can’t push the straw inside like he does on others. He can’t leak true contents all over himself like all of the other others. He can even drink holding the cup upright like a bottle where the others cannot. I have bought many of these. They are easy to clean. Lid functionality is incredible. Literally never leaks. Fits perfectly in sides of backpack and in cup holders. Comes in cute designs. Best purchase!

I absolutely adore these cups, they hold a significant amount of liquid. Also when flipping them over they do not leak, but once using them for about a month or two I noticed there was small leakage coming from the straw. If there is cold liquid in there and it starts to warm up the pressure from the inside will make the liquid come up from the straw causing it to leak. Overall, these cups are cute and durable but there is some slight leakage. It is dishwasher safe and the straw in the inside typically do stay intact even after my toddler throws it.

We love the Zak Designs Kelso Tumbler Set! These cups don’t leak at all, and with our 3-year-old, we’ve never had any issues. They’re easy for little ones to use and have been fabulous overall. That said, our second child has shown a small design flaw: the rubber straw can be pulled out, which sometimes leads to spills in her car seat. Also, after about a year of dishwasher use, the designs start fading and peeling. Overall, these are still great cups and we’d recommend them—just wish the straw design and durability of the print were improved.

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!
