Features

  • SIZE: The set contains two Bluey tumblers that are 3.16 inches in diameter and 6.67 inches tall. They have a capacity of 15 ounces.
  • MATERIAL: The durable tumblers are made of plastic with silicone straws. They're dishwasher safe and should not be microwaved.
  • LEAK-PROOF DESIGN: The silicone straw has a built-in valve that allows liquid to flow when drinking and prevents accidental spills when the tumbler is tipped over. The straw is also soft and comfortable for kids to drink from.
  • AT HOME OR ON THE GO: The straw tumbler is suited for travel, since it won't leak and fits in car cup holders while keeping drinks easily accessible. It's also great for drinking beverages at home without worrying about stains or nearby electronics.
  • LIFESTYLE: Zak Designs drinkware makes hydration fun! These Bluey tumblers are a great gift for any fan or kids just graduating from sippy cups. The tumblers are fully reusable--no more disposable cups--and a fun addition to the daily routine.

Description

Does the Kelso prevent spills when the tumbler is tipped over? 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. Is the tumbler easy to clean? 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. How old should my child be to use the Kelso tumbler? We recommend this tumbler for kids age 3 and up. What kind of drinks can go in the Kelso tumbler? 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. Can I travel with the Kelso? 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. A little joy goes a long way. It's wild and fierce, a massive force, or sometimes it's the little things, like a smile or your favorite color. Joy is meant to be shared; it's an amazing feeling and you deserve to feel it every day. If we can be the ones to do that, then nothing would make us happier.

    • 🕷️ Perfect for Little Superheroes – Durable, Fun, and Truly Leak-Proof!
Color: Spidey and His Amazing Friends Size: 15 Ounces 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

    • THERE CUTE
Color: Bluey Size: 15 Ounces Style: Drinkware
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. ... show more

    • Don't let the cute patterns be the only reason you purchase these cups
Color: Silly Goose, Harvest Size: 15 Ounces Style: Drinkware
I'd give it a 5☆ review if the patterns held up to the usage, but I knew that when I bought them. The quality is still great. Up until now, I had just purchased the basic, smaller Zak cups from Walmart until I saw how well they would work for my child. My son is 17 months old, and he's been using these cups for several months. They're a great cup for a tiny human that has an understanding of how a straw cup works because there is no weight/flow adjustment. We moved to these when he got tired of Chicco straw cups. The green "goose" cup is my son's favorite right now. Unfortunately, you can't tell that there's geese on it. I don't put these cups in the dishwasher, but the patterns still don't survive the daily wear and tear of a toddler. Otherwise, they're a great buy. They don't leak unless you place pressure on the straw itself. So if you're wanting something that your child can throw down, toss around, and pick back up again without a puddle being left in the floor, these are a good option. I'd also like to point out that the straw is silicone, and if your child goes running around and falls, the cup itself may be painful to land on, but their mouth isn't going to get cut up from a plastic straw. Cleaning the cup is super easy. The top, and straw are dishwasher safe, and it breaks down easily for cleaning in the sink or a quick rinse. The body of the cup is not dishwasher safe and has to be handwashed if you want to keep a shred of pattern on it, but like I said, daily use and wear eventually start to show. These cups are colorful, easy to clean and they're a good fit for a tiny human who is ready to transition from a weighted straw to a regular straw cup. Even if the patterns don't hold up for very long, I'm happy with the purchase. ... show more

    • Impossible toddler tested- APPROVED!!!
Color: DinoRoar & Zaksaurus Size: 15 Ounces Style: Drinkware
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! ... show more
