Zak Designs Zaksaurus Kelso 12oz Stainless Steel Leak-Proof Toddler Cup

Started using these for my son's milk. He is 2 years old. So far they work perfect. They're cute, keep his milk cold, easy to clean. I haven't had issues with spills. Great product?

Love this cup! Its insulated and the perfect size for toddler. Does not leak but sometimes pressure can build and will come out the straw. Easy to use and clean. Exact color shown.

This was such a hit with our daughter! She was immediately excited when she saw all the princesses around the cup, and now she wants to use it for everything—water, milk, even juice. The design is super cute and wraps all the way around, which she loves because she can spin it and point out her favorite princesses. The cup itself feels really well made. It’s sturdy enough to survive drops, keeps drinks cold for a long time, and has been completely leak-proof for us so far (even when it gets tossed in a bag or knocked over). The size is perfect for a toddler—easy for little hands to hold but still holds enough to get through outings or bedtime. One small downside: the straw has a few pieces, so it takes a bit more time to clean compared to simpler cups. Not a dealbreaker at all, just something to be aware of. Overall, this is a great gift and we’d absolutely buy it again—especially for any princess-loving kid! 👑✨

This is honestly my dream toddler cup. It actually doesn't leak (I mean unless my kid if vigorously shaking it upside down, and even then it's minimal). I had issues with other cups where the liquid would come up out of the top of the straw and puddle around the cup. This one does not do that. The top silicone straw pops in and out easily so I can wash it and let it dry. Keeps the drinks cold and I no longer have the issue of the cup smelling weird if anything goes in it besides water. Definitely would recommend to anyone with a kid and would make a great gift. I just wish they had a toy story one in this style!!

We’ve tried 6 to 8 different types of straw cups with our 20 month old, and this cup, along with Owala and Infanto, are the only ones that she could drink easily from and are TRULY leak proof. We use this cup for milk when she’s playing on the floor and for road trips, since it’s insulated and can stay cold for longer. It’s also easier to clean than the Owala and doesn’t need to be taken apart constantly (which breaks the silicone down quicker), so for that reason alone, we prefer this cup. My only complaint is that it’s difficult to get the last bit of beverage out, since the straw sits in the middle of the cup instead of along the edge like the Infantino tumbler, so we always have to pour the rest of her drink into the Infanto so she can finish it. Overall, this is our favorite right now, but if Infanto ever comes out with a vacuum-insulated metal tumbler, that one might take the cake.

This is a great cup and my kid loves it! Pros: It's very to take apart and keep clean, keeps drinks cold and ice doesn't melt too fast. And the little design is really cute. The only con is that if your toddler holds it upside down it will leak a little bit out of the straw. Also I feel like everyone should know but in case not.. you need to take it apart every night and wash it and let each piece dry separately. Insulated cups like this can grow mold if wet pieces are out together. Overall it's a good purchase. I really like Zak products

I have spent a lot of time trying to find a cup that doesn’t spill that my toddler can use on his own. This one is perfect! The straw is a little bit tough to suck from, but he figured it out so fast and it actually slows him down so he doesn’t drink too quickly and choke. The cup is insulated and keeps the drink cold. I put ice in it and it lasts for hours. The straw comes out and the silicone straw and piece that prevents leakage also comes out which makes this cup so incredibly easy to clean. There aren’t any places where mold can grow and hide. I did notice a few drips would come from around the silicone on the top if the cup had been tossed around, but not enough to complain about or take away a star. The design is so cute and so far hasn’t faded or chipped after washing. It says dishwasher safe, but I have washed it by hand. 10/10 would recommend this cup and I will be buying more!

Great cup for my 1 year old. Leak proof and love that the inside is not plastic. She has dropped it several times and no dents. Good strong cup. It took her a little to figure out the straw but after a day she figured it out.

Está super cute el diseño y es de acero inoxidable. Es ligero y los niños no batallan para agarrarlo

Bought it for my daughter and its her favorite cup. She loves Gabby's Dollhouse and Cakey is her favorite character so it's an absolute win. Hasn't leaked, super easy to clean and toddler proof

Besttt! Love that it all comes apart for cleaning and they have been so durable ! My toddler throws it around pretty wild sometimes and it’s held up! Minor leaking once the straw starts to wear out but I ordered some replacement straws that fit great! Love the stainless steel, wish the inside straw part was stainless steel as well but hey a girl can dream lol

Vino con caja, se agradece

Love the design and stainless steel! My son loves this cup and I love that it doesn't spill much and keeps things cold for longer amounts of time than the plastic alternatives. Would purchase again without hesitation.
