Sturdy and perfect size for my 6 & 7-year-old boys, They love spiderman but they drop their cups all the time. Very sturdy and mostly leak proof.

This is a great two-pack of cups! Very cute designs. The lid screws on and is leakproof. I filled up the cups with ice water at night to test them and there was still ice the next morning. Easy to hold for my little ones

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!

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!

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.

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.

No spill! Easy for little ones to hold.

My daughter absolutely loves these cups!! We got the lilo and stitch set of 2 cups and they are adorable. They are the perfect size for a little kid and keeps whatever drink you put in there nice and cold for hours. The only thing that could make these cups better is if they had a retractable straw.

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.

I was actually skeptical when I ordered these. I have bought so many cups over the years for my grandkids and they leak everywhere. I've always had good luck with the Zak brand so I figured I would try these. They are shaped like my cup and everyone wants to drink from that so I bought them. I was pleasantly surprised that they didn't leak!! Easy to clean. Like all of these stainless cups they are so dang loud when the toddlers drop them but that's to be expected. I'm very pleased with my purchase. I hope to buy more! I do wish there were more options for boys.
