Plastic Kelso Tumbler

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!

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.

Our daughter loves them! Great durability, easy to hold, and last for awhile. Good size and great easy to use first cup for transitioning our daughter away from bottles. We hand wash these which is easy. We like that they don't leak so when knocked over we aren't running the pick it up before it all spills.

My son absolutely loves these, and I don’t know if it was just a coincidence, but he was completely off the bottle within a week after introducing him to these cups! So far we have not had any issues with leaking (as long as you make sure the lid is screwed on completely) and they have withstood quite a few drops and throws. very easy to clean, which is a huge bonus as well! I wish they came in solid colors or just patterns instead of character designs, although I do love the Dr. Seuss print that we got. Excellent price, 2 for $15. I don’t think these are known for holding temperature, as they’re plastic and not insulated I believe.

These cups are really cute and the designs are adorable! I also love that they hold a good amount of milk, so I’m not constantly having to refill them. They’re a great size for toddlers and easy for little hands to hold. My biggest issue is that they do leak, and the straw seems to come loose pretty frequently, which can get frustrating and messy. I still like the cups and use them, but I wish the straw stayed securely in place and they were a little more leak-proof. Overall, cute and functional with a couple of design flaws!

The best cups so far. My toddler loves them . Best for thicker fluids,and water for my baby. Spill proof and easy to clean. Ordering another set soon. Soft outer straw so you dont have to worry about it hurting baby. He can use it while standing or rolling on the floor

Ordered two sets of Toy Story and love them! The design is adorable and they really are leak proof. Another bonus is the fat straws on the inside. It’s big enough to put on the little “spikes” in my dishwasher so it stands upright and I don’t have to use a straw cleaner to handwash the inside of the straw. The price is reasonable as well and we love the fun colors. Fits a great amount of liquid inside for my 3 year old.

I have tried various straw cups, and these are my toddlers favorite. I love that the straw is big, only has three parts, and completely comes apart for easy and thorough cleaning in the dishwasher. I use them for both milk and water, and they have never had a sour smell. Highly recommend.

Bonitos, buena calidad, no derraman y son fáciles de limpiar.
