Review on 🏜️ Thirstystone Desert Sand Coaster - Multicolor All Natural Sandstone, Durable Stone with Unique Patterns, Original 4 inch Round by Matthew Baltimore

I like them, I'd like them in different colors or with a pattern on them. They absorb water from the sweat on my glass. I drink water with a lot of ice, so a lot of moisture comes out of the glass and usually leaves big wet stains on my table. Other coasters no longer stack and then overflow instead of go, they absorb moisture. I highly recommend them. After using them for a while I found that if you didn't let them dry completely they would start to get moldy for lack of a better word because the stone retains moisture. Very difficult to clean, I change them regularly now, I drink a lot of ice water so they sweat a lot. Dyes the stone and they stopped working too. It was originally five stars.
