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.

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.

These princess glasses are perfect for children. They hold ice, keep drinks cold (or warm), and best of all, they are spill-proof! The cup fits in drink holders, the lids screw on, and the silicone straw fits snugly. The squeeze to drink feature of the straw makes it truly the most spill-proof cup my grand-children have ever used. The Disney princesses, cute colors, and handle are great as well! Don’t let these slip away!

These cups are absolutely adorable! They are perfect for kids (adults could use them too, but I'd prefer one a bit bigger for myself) as they aren't too big for smaller hands. The soft upper straw is an awesome feature for little ones as it's safer than the hard alternatives. They definitely can keep a drink cold for quite some time. I made ice water and left it overnight. After about 12 hours, it still had ice in it, so the insulation is awesome. This is a nice, quality cup with fun designs!

How cute are these insulated cups! I bought these to give to my students as a reward for good behavior. I decided to wash them and put ice in them to see how long the ice would stay solid and I was pleased to find out there was ice for many hours! Well made and super cute design! I’d certainly buy them again!

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.

This tumblers are so adorable. The color, size and the size of the handle are perfect for small hands. The design are so cute , all the Princesses . Love the color too , peach and purple. But most of all it’s leak proof. So you don’t need to worry in the car seats or strollers .

My whole family love these! I really love them for my 1 year old he thinks he is so big. So i love that the straw is flexible on top so it doesnt hurt him. Really love that no matter what age is using it they arent leaking water all over when its forgotten. They have withstood being dropped so many times! Just get them!

I love the quality and size. It’s not too big and not too small. It’s good for kids, for toddlers kind of hard to use the straw. I love the LILO and Stitch and the Angel cups. The purple one is Angel so that’s my favorite. I like that it keeps drinks cold and that the cup is leak proof.

He's obsessed with this tumbler! It keeps his drinks cold for hours (and hot when need it), and it doesn’t sweat or leak. Super sturdy and perfect for on-the-go—whether at the park , or just relaxing at home. The design is cute, and it fits perfectly in a car cup holder. She use it every single day!
