Review on Mothers Day Gift: Sandstone Absorbent for a Thoughtful Present by Anferny Pineda

They have a cork backing, not a felt backing as shown in the pictures. I ordered these pads in felt, not cork, but now that I've used them I'm glad they came with cork. They get incredibly cold when cold drinks are placed on them, which is pretty funny. I haven't noticed any "sweat" on my drinks since we used them, but didn't look for it, which I think is part of the attraction. of these. They are very beautiful too.
