Review on 🌈 Color-Changing Cup Straws and Lids by Tim Blandin

These cups are nice and thick. Colors become very intense when the liquid is very cold. The lid snaps on nice and tight and the straw has a stopper so it doesn't pop out all the way unless the lid is closed. I put 1 in the dishwasher and it didn't melt or warp, and the heat didn't affect the color of the mug when the cold liquid was put back in the mug. Also, it comes with a straw cleaning brush and a foam brush! Good color variety. I would definitely buy them again!
