Zak Designs Disney Kelso Tumbler 15 oz Set (Minnie Mouse) Leak-Proof Screw-On Lid with Straw, Made of Durable Plastic and Silicone, Perfect Bundle for Kids

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!

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.

We have several Zack cups in our home and our daughter’s home ! First: this is an excellent cup. No spill and lives up to that claim. ! Second our little one loves it and she learned quickly to sip from a straw with this. She has thrown it, dropped it and NO spill, no cracking Highly recommend. Great design. Removable straw to clean. Cannot say enough positive things about it.

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 / 5These 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!

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.

These cups are a lifesaver! Completely spill-proof—even when my toddler throws them or tips them upside down, nothing leaks. The straw is easy for little ones to drink from, and the design is sturdy enough to handle daily use. They’re also simple to clean, which is a huge win for busy parents. My kid loves them, and so do I. Highly recommend for anyone with toddlers!

We’ve tried a lot of straw cups. I read reviews and saw other parents recommended this brand. They work great for our 13 month old. The best part about these cups is that there’s 4 parts and it’s easy to clean and reassemble. They aren’t completely leak proof but they do a really good job at being close to it. Time will tell how they hold up but I’ve already repurchased these cups twice because of their functionality. The designs are very cute and I appreciate that the cup and straw is somewhat see through so I can see if my little one is actually drinking. Also, I did a drink test and the straw seems to not be too easy or too difficult to drink liquids through. I wish they had some measurements on the side but other than that 10 out of 10. Definitely recommend getting these.

Easy to clean? Yes (too easy since the graphic comes off). Easy for a 1 year old to use? Yes. Leak proof? Not completely. Design? Beautiful but rubs off EASY. Had it not been for the functionality of these zak cups, I'd have given them a 1 star due to the design being easily rubbed off.I *have not* put these in the dishwasher. I've hand washed them and after seeing the design getting scratches on them after just a couple weeks' use, I used a soft sponge or wipe for the outside. The blue ones we got at the end of January. Just 5 months old. As you can tell from the picture the graphic is almost completely gone. The red one was given to us on Easter. Barely over 2 months old and you can see how much the graphic is already damaged. My son has one with him in the car, when we go out to eat, in his stroller when we go to the park. He loves water. So they aren't used lightly. But even now, I can lightly rub it with my nail and the graphic will come off. Disappointing in that sense.The cups have been durable, otherwise. No insulation capacity at all. Value for money- a little over priced considering the graphic damage. Functionality us a 7/10.
