Are these of any value? I'm 99% sure theyre clay and most likely Paulson, I got them with about 1000 fun nites, a paulson color samlple set, a bunch of paulson acrylic trays, and some other misc paulson stuff from a failed dealer school. Theres 17 each of the 100, 500, and 100, 1 OFF and 2 LAYS, its pretty much all I have left from everything
