Color Changing Cups 10Pcs 12oz Plastic Tumblers With Lids and Straws for Iced Coffee Smoothie - Reusable Leak Proof Party Cups for Kids

Durable plastic and easy to snap lids w straws. This was used for party favors and everyone loves the color changing. We use the leftovers daily. Easy to wash. Use toprack dishwasher or let air dry. I would air dry the lids so the heat on dishwasher does not warp lid. After a month of using this, the color changing still works. These have been dropped on floor by toddlers and they have survived without any cracks.

These cups exceeded my expectations, I ordered a total of 30 cups. They arrived quickly. The color changing with ice water is so fun. Got them for my daughter’s 10 birthday party and they were a big hit. Perfect size for kids, they don’t leak and the lid is easy to put on. I personalized them for each person at the party for a lemonade bar.

They are perfect for toddlers and young children. The kids love making the colors change. Some cups react to heat and others react to cold. They do leak from the straw hole in the lid if they are tipped over, but they are pretty sturdy for the price and easy to clean. Helps keep drinks organized too. Each kid gets their own color and we don't have to worry about them drinking out of each other's cups.

I purchased these for a girls trip. I thought they would be bigger than expected. They are an average size 12oz cup with straw as described. Very durable and fun colors. I mixed matched the tops and straws that came with it. I took a picture against a regular glass for size. They do however fit in a 10”x7” bag. Great for kids parties! Value was worth it!

Used these for a kids birthday party and they worked great. The color changing is also fun.

I love these cups!I purchased these as a birthday party favor and had two left over. They were a big hit! The color changing is awesome, the lids snap on securely and everything is good quality, including strong straws. The size is good and I like that they're perfect to use with lid off, also.. no threads or anything that would be tougher to wash.Fyi some of the colors change slightly over time. Like the green (after 6 months) looks a bit more blue/teal, but totally fine with us.I'm going back to buy more to use as every-day use kid cups.

I have used the thinner cheaper plastic cups for my grandkids for years. You know the type - they come with a straw or a sippy lid. But these are a huge improvement. The lids are a little tricky to snap on, BUT they stay secure. They are also larger than the cheaper, thinner plastic ones I used to buy. The little ones also get a kick out of the color changing aspect with cold liquids. I’ll never go back to the old style.

I bought these for my grandson and while they are very cool, the plastic lids are very rigid and if dropped break very easily.
