I have never seen a Cameo glass piece this thin before. I would imagine that there are not very many that are because it would be very difficult not to break the piece while carving on it. The bottom has the letters "FLUP" If anyone knows what this means please message me. Another new one I had not seen before.Excellent condition with no defects to note. I take close up photos and feel they describe the item better than any description I can provide. Please examine ALL photographs for further condition details.
