Zak DesignsKelso Toddler Cups For Travel or At Home, 12oz Vacuum Insulated Stainless Steel Sippy Cup With Leak-Proof Design is Perfect For Kids (Fanciful Unicorn)

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.

Doesn’t leak, easy to clean, durable, dishwasher safe and super cute

This cup is very easy to use, take apart and wash. It keeps the beverage cold longer than the regular plastic Zak cups. It hasn’t leaked at all and we’ve used it a lot. The only negative I would say is when you put the cup in dishwasher the design peels over time. DO NOT put the top straw part that you drink out of in the dishwasher because that will make it leak.

It does not leak and I like that it has a stainless steel interior. Cute design and great for on the go! One small thing for me has been sometimes I have to adjust the straw on the inside because she isn’t able to get a good suction, but then it is fixed and works great.

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.

Washes well in the dishwasher, made the granddaughters smile, straw is easy to keep clean and the cup keeps liquids cold for a good bit. Packaging was great and the colors are vivid. Cute cup for a gift and can been used every day!
