Zak Designs Disney Frozen II Movie Kelso Tumbler Set, Leak-Proof Screw-On Lid with Straw, Made of Durable Plastic and Silicone, Perfect Bundle for Kids (Frozen 2 Olaf, 15 oz, 2pc Set)

My toddler needed a new milk cup, and we wanted to try something new, so I purchased this Zak Designs cup. We have been using it for only a day, and so far, so good! There are no issues yet. The straw inside is bigger than other brands, which is great. It is a nice plastic cup with a cute Bluey design that my toddler absolutely loves. It has no leaks and is easy to clean. A very good purchase!

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!

These are so great. These bottles are great for water, juice or milk for little hands. I’d say ages 2-5. My daughter just turned 4 and loves the Zak bottles. I love them too because they are easy to clean (we take off the top rubber mouth piece, lid and straw, and place it in the dishwasher); they are easy for her to drink from and she loves the designs.

I gave these cups as birthday gift for a 2 year old. The cups are very sturdy and easy to use and the size is perfect for toddlers and the colors are just as described.,, no leaks

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.

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.

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.

They are spill proof but if you hold it upside down and shake (like my toddler does) it will leak from the tiny air hole. Not a huge mess just a few drops. Still a very good quality cup. No weird plastic after taste.

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

Está hermosos súper buena calidad, ideales para que empiecen a dejar el biberón

Great product!

This was our first purchase of Zak cups (2024), we loved them so much we bought another pair in 2025 and just received our third pair now (2026). The OG ‘24 cups are still kickin and have survived through the beginnings of toddlerhood and the thick of it now! Their design has worn off slightly, between the dishwasher and just general wear and tear over the last 2 years. Otherwise the cups are still going strong in terms of leakproof! The same goes for the ‘25 set as well! Our son loves them so much! 100% recommend!
