Keith, Cebloplast is one of my favorite materials I wish I had bought more when it was available, all I have left is 3 rods of serpent, I lost Elliot Landes address, he did have some of the cracked ice in blocks. I have to agree your pens are very beautiful, I favor the Ruby Red, it's hard to believe that Mazzuchelli made that material so long ago. I wish they would make it again. (but maybe just a little easier to drill)
