Color Changing Cups with Lids & Straws - 16 oz Cute Reusable Plastic Tumblers Bulk | 9 Pack Party Funny Tumbler Ice Cold Drinking Cup for Kids & Adults

These cups, lids, and straws have held up well since I gave them to my grandkids. It is possible for liquid to leak out of them since the straw is slightly smaller than the opening in the lid, but the lid snaps on securely and doesn’t allow any leakage around the rim. My 3 and 5 year old grandkids love the color changing feature. I am very happy with the durability of this set, and I highly recommend these color changing cups, lids, and straws.

I love these cups! They are thick plastic cups that change colors when they get cold. The straws are also thick and comes with2 straw cleaners that's awesome. The lids can pop off if dropped is the only con for me. (Hint after washing cups and they dry the cups are all white, to see what color they are simply put empty cups in freezer for a minute.)

I really hoped ALL the colors were as vibrant as the photos. I had good luck with most colors but some were kind of blah! I bought 2 sets as favors. First photo is one set filled with cold water, second photo is after I dumped out the water, and third photo is the second set filled with cold water. The colors that were really vibrant were the yellow, teal, dark blue, pink and gray. The not so great colors were red, orange, green, and purple. Also, both packs had 2 of the cup cleaners but none of the straw cleaners. I will be customizing them so hopefully the kids don’t mind too much!

They are great. I used them as part of the favor bag for my daughter's party and the lid snaps closed. They change to bright colors once you add really cold or ice drinks. It is kind of difficult to differentiate between some of them when dry, but once you add some ice water, you can match the lid with the cup.

I was worried at first… I didn’t think they worked. It takes a few minutes the first time they change color. They are awesome! My kids love them. They have e dropped them, been normal kids with these cups and they have held up. They are sturdier than I expected. The straw fits well in the hole on the lid… so while it’s not leak-proof, unless my kids tip it upside down, they haven’t leaked.I might get another set to give out at a birthday party. They are really cool, the color is bold and are surprisingly well made for this price.

Purchased these for a sleep over so everyone had reusable cups for less waste and no confusion as to whose was whose. Best decision ever! It’s been 8 months and they are still using theses cups with lid and straw almost daily😍

The media could not be loaded. These cups we use for smoothies and they’re so cool! They’re all clear and once the coldness comes in contact the cup changes color. The colors are so pretty too!

I was excited to receive these and use them for my kids. It was cold outside, so I could see the colors of the cups right away. The colors are pretty vibrant. Something that disappointed me was that the lids don’t necessarily screw on, they snap on. They seem really loose fitting. They are fun cups, but if you are buying these for your kids as leak proof cups, I would steer clear.
