Great for kids!

These stainless steel cups are perfect for my 12 year old son. He is always wanting to take drinks in his room and now I feel better about that. These cups keep his beverages cold and from spilling.

Leak proof kids cups

The cups are super cute. Totally leak proof. Easily cleaned. Just the right size for my grandsons to handle and carry. Loved that the silicone straws are attached makes keeping up with them super convenient. Definitely worth the price.

Great on the go cups!

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

I do not at all like the fact that there is a ball of lead in the base of these tumblers and that it could possibly dislodge and cause permanent damage to our children possibly death

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!

Perfect size and sturdy for kids

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.

Not Leak-Proof

These are 100% not leakproof. I wanted them to be so bad! Ugh still on the hunt for a non-leak proof water bottle! They are very cute though.
