When ordering, you must ask for the design to be polished on the inside though, and you also must always prime after every use. They come in 18" lengths and you design the shape. Then they cut into heights of 1" or 2" or 1-1/2 " . The smaller the height the more you get out of the 18" piece. The initial expense is high but if you go in with a group and order , in 1" tall pieces, you should get quite a few.

This product is still fragile if not handled carefully and will chip, so take care with these and they should last MANY firings. You MUST prime each time though. And I suggest to pre-fire them and then prime.
