Review on Premium Large Drink Coasters: Moisture Absorption and Table Protection - Set of 6 Modern Black Rubber Coasters with Non-Slip Bottom for Drinking Glasses by Lisa Wilson

I bought these because they looked like the PERFECT coasters I bought from a pottery barn many, many years ago and love. it's very different. They appear to be made out of the same type of rubber that I think a Halloween face mask or rubber nose would be made out of. The bottom of the stand is unfinished, as is everything else. The bottom is a very shiny black rubber with raw edges and if you want to move it around the table. well good luck with that. You have to take it off the table and then put it back in the desired place. I ordered 2 sets and threw them both away. I was so annoyed by the poor quality that I didn't even want to deal with sending it back. they belong in the trash.
