Review on Juvale Round Slate Coasters Set by Ricardo Ware

Disappointed with these. They were well packaged, all intact, but when I took them out and tried to put a cup on top, I found all but one were swaying. You can't safely put a cup on it without fear of it tipping over. After reading that some people complain about uneven thickness, I compared them all to see that not all the stoppers on the bottom of the coasters were the same. Sounds like a silly manufacturer error. They have been returned.
