My kid is obsessed with Minecraft and is always stealing my water cups even though he has his own! He really likes a handle, I guess. These are great because they're fully dishwasher safe. The screw top lid is easy to use, and it's not too heavy at 16oz for him to carry around. It's cup holder friendly, including for his graco car seat. As expected, it keeps drinks really cool! He was sipping on the same chocolate milk for two hours the other day and it stayed cold in this cup.

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.

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!

I absolutely love these cups! ZAK is a great brand of cups and I really love how they keep things cold for a long time ! My girls use them at daycare and school and they keep their ice all day long. The Stitch print was an extra bonus for them! Very cute !

Great cups for kids! Holds a little more than 16 ounces. Love that the top of the straw is rubbery and not hard plastic. The cup is designed to be leakproof and I can attest that they do not leak! Comes apart easy for washing. Keeps Ice for about 8 hours! 100% would recommend for kids!

The quality is excellent, feels sturdy and durable, and it’s held up well even after a few accidental drops. The lid seals tightly and prevents leaks. I also appreciate that it’s easy for little hands to open and close, which helps my child feel more independent. The straw design is kid-friendly and encourages more water drinking throughout the day. It keeps drinks cold for hours! We’ve used it for both water and juice, and everything stays fresh and cool. And of course, the cute design makes my kid excited to use it. Cleaning is easy too—I just rinse it out and occasionally throw it on the top rack of the dishwasher. No weird smells or lingering tastes. Overall, this tumbler checks all the boxes: safe, spill-proof, long-lasting, and kid-approved. Highly recommend for parents looking for a reliable and fun drinkware option!

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.

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 .

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!

My grandson loves his cups
