Review on Sonku Coaster Set for Absorbent and Glass-Friendly Surfaces by Larry Morris

I really liked the quality of these coasters. I bought these to put under potted plants and they are perfect. They are thick and seem very durable. I'm not sure how absorbent they are because I haven't had any leaks since I bought them, but they're definitely what I've been looking for to protect my windowsill paint from chipping or warping.
