Best child’s no spill cup

Better no spill cups for kids than any of the other brands including yeti. Much easier to clean. No spills. Nothing to brake. I won’t have to replace them till they wear out. Great product finally at a much better price than Stanley or yeti, twice as good.

Stitch tumblers

My daughter is crazy about Lilo and stitch and loved these water bottles. They are really durable, and they don't leak. She carries them around with her everywhere, and I have had any issues with spilling. The design is super cute and really high quality product

Awesome Cups

The grandchildren love them because they have Spiderman or Disney Princesses on them. Grandma loves them because they are practically spill proof. It's a win-win for us!

Great Gift

I bought the Hello Kitty set for my daughter & she just loved them. The tumblers were not to big nor too small they were just right. Not only are they durable they keep your drink nice & cool for hours.

Great for littles

Love these cups. Always been a fan of Zak! products. 2 packs works great for twins so they don't fight. The quality is great and can't wait to see how these hold up. The flex straw is great for littles who can't hold the cup upright and the inner straw can be easily cleaned.

Great colors and very easy to clean!

Great for kids! I gave these to my niece and nephew. They loved them ! They saw them and wanted to use them right away. Staying hydrated is great! The quality is superb and they look so good. They were easy to wash which is a great plus when it comes to water bottles and water containers.

The only cups my kids need! 🙌

Adorable, sturdy, keeps drinks ICE cold, no condensation and leak proof! You can’t go wrong with these character cups!!!! You can mix and match the lids, and my kids love these as much as I do! I have a toddler who turns his cup all over the place and every which way, and I love it because that’s ok with these! Also the biggest bonus to me is that they are dishwasher safe. 😍

Great cups but they can leak.

My daughter really likes these cups and so do I. It holds a good amount of water and keeps the water cool. The inside straw is detachable so it can be washed properly. It does require a decent amount of force to suck the water out due to it being a spill proof straw. I have noticed if there is ice water in the cups and they are left on their side they do leak out of the straw a little bit.

Cool tumblers for cold drinks!

These tumblers feel like a good quality product and they look great as well. They do keep drinks cold for a long time (see photo of ice water after 14 hours as a test - there was still plenty of solid ice left!). The straw assembly pops out easily for cleaning and they are top rack dishwasher safe which is a bonus. These also don't spill if turned over due to the vacuum sealed lid/straw design so very kid friendly.

Nicely insulated but…..

These were very cute for my 10 year old nephew who loves Minecraft. I liked the 16oz size and it does insulate cold very well. The spill proof straw is a great idea and the top twists to close which is nice. The downfall is the straw. It’s a rubbery material and my nephew chewed on it. It’s also hard to clean. Overall a good product, but I will need to get a different straw.
