Exactly as pictured and described, although I wasn't necessarily expecting each one to be different, but that's ok because I like that even better, they seem more unique and special. Love. They are indeed quite thick, more than your average coaster, but that's not an issue for me.
I bought two sets for a friend for Christmas and liked them so much I bought myself two sets as well. I was disappointed that when I went to order my set the square coasters were no longer available, but the round ones work just fine. They are pretty high, just under half an inch. They look just like the pictures and fit in with my reclaimed furniture perfectly.
