These are actually 12 Oz, not 16 Oz.

Perfect size for young children. Lid screws on securely.

These cups are ok, cheap enough if you loose them, come with straws which is nice, covers can be a smidge hard to put on.

Cups are durable and cute, i would of gave a 5 star but the lids are kind of hard to get off and on.

The kids loved these. They especially liked the color changes. Just the right size for little drinkers.

The cups only came with 5 straws and if the are tipped over the liquid will spill out. The children do enjoy the color changing!

These cups are great! My son totally loves them. Great size and easy to clean. Lids fit nice and snug so they won’t pop off if they are dropped.

I love the designs and color changing works well with vibrant color. However, there is only one thin ring around the top of the cup that the lid is supposed secure onto and for the life of me I could NOT get the lid to stay on. Only one side would secure and the other side would pop off. Pretty much useless unless you want the drink spilled everywhere by your kid.

The cups leak from the lip if full

My little one was so excited to be able to mix and match the colors.
