Zak DesignsSesame Street Kelso Toddler Cups For Travel or At Home, 12oz Vacuum Insulated Stainless Steel Sippy Cup With Leak-Proof Design is Perfect For Kids (Elmo)

Beautiful design, very easy to assemble, disassemble and clean, holds cold liquid for a long time. It’s large enough for my kid’s serving of milk. Doesn’t leak as long as the rubber seal is intact. This is my 4th Zak! cups that I have purchased for my son. Durable and good value for the money! Will definitely buy more!

Super cute cup, my toddler loves the Elmo design and wants to carry it everywhere. It keeps water cold for hours and is mostly leak-proof (a few drips if the straw is squeezed, but nothing major). Durable, easy to clean, and perfect for daily use. Would definitely buy again!

Ok this is the cutest cup. Great price. No leakage. It keeps drinks cold and is easy to clean. You can order replacement parts - which I love cause my daughter chews on the end of the silicone straw piece. It holds a good amount of liquid and the lid screws on. Again, super easy to clean. I put the cup and lid in the dishwasher but I wash the silicone straw piece and the straw inside by hand - but I just use a straw cleaner for that and I am done in 10 seconds.

Love this cup! My son started using it at 10 months old. (I did teach him how to use a straw with one of those bear cups). We’ve had this cup for 6 months now, still has not once leaked (other than the little droplets left in the tip of the straw), keeps things cold, has kept milk warm, my son started holding it on his own right away. I through it loose in my bag and never worry about leaking, I give it to him in the car and never worries about spills. Love that it’s stainless steel and silicone, the only plastic is the lid.I literally tell every mom to get this cup.

Love this cup! It does not leak and it’s perfect for toddlers. It’s very durable and 16 month old loves it. Only reason I can’t give 5 stars is because the design WILL completely wash off. I’ve had washed all mine and every single one has completely lost its design. Wish they could fix this, but otherwise great cup.

After buying the regular Zak cups we got this one to keep to her milk cold longer. Which it does. It is spill proof and is easy to clean. I don't think it keeps stuff cold for hrs on end but it's perfect for those shorter trips. We love the design and find it is a little heavy for our 1 year old to hold but she figures it out.

My daughter loves this cup - so cute and it keeps her drink cold for hours! It is 'leak proof' to an extent, just like all other toddler cups, none are truly leak proof. If you put a drink in the fridge and then take it back out, the liquid does come back up thru the straw. I do also wish they made replacement valves available to purchase because they do eventually break with washing and then they leak everywhere. I had to replace the whole cup instead of just the valve, seemed wasteful.

Just get it!! Totally worth it. Durable, we have had them for 1+years and no leaks yet! Easy to clean, I even throw them in the dishwasher most of the time!
