When you get them, just be careful which section you use to make the pen. I believe these must me knife scale blanks (the ones from PSI), because they are an odd shape. When I used them, I made 2 pens from one blank. One had a distinctly better leopard print than the other (the section of the blank with the smaller dots). In hindsight, I would order two blanks if you are doing two pens. Just my 2 cents.
