Review on 🌈 Optimized Color-Changing Cold Drink Cups by Joseph Lang

Much better when I bought these than a Starbucks mug which has sold out everywhere and is now for sale on eBay for over $100. My daughter (14) loved the interchangeable cups so I bought her this set. She was pleased with the color change and the fact that she had five instead of one. Great gift for teenage/teen kids, especially kids who have everything and you have no idea what to get them and maybe, like me, don't want to spend a fortune dreading the cost of college.
