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

Cold liquids absolutely change color of these cups! Vivid pinks & purples, blues & greens, our granddaughter loves these & recommend to all fun loving people!

Some of these cups change color, some don't. I followed the instructions to activate the cups but it didn't make much difference. Some of the lids also come off a little to easily for use with younger kids.

Honestly a good product overall. My 5 y/o son loves them but warning to moms. If you have a picky kid, the cups are mostly translucent and the color doesn’t show up until it’s cold so picking the right color lid and straw to match the cup can be tricky (my son gives me a hard time over it occasionally). They are a great cup for kids transitioning from a sippy cup but aren’t quite ready for a regular cup yet (or for mom’s occasional iced coffee 😉). So they are not spill proof but they do prevent large spills. Nothing special but a fun cup overall!

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!

Me gustaron mucho pero las tapas vinieron mal y no puedo ocupar 2 vasos con sus tapas xq no les quedan, es una lastima xq realmente me gustaron...

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!

Cute durable cups lids and straws that change colors.

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.

Son muy bonitos, muy coloridos y buen material,súpero mis expectativas .

Cups aren’t nearly as vibrant as they are In The pictures
