I have quite a few blanks that I purchased from "Bethlehm Olive woods" (i'm not recommending them by any means) that came with the certifications. They are little cards that were printed on hard stock and cut out. Something that anyone could print up using a print shop program. Nothing special about them other than the fact that they came with the blanks. I could easily print some up and make them myself but to me that seems a little unethical. At least when I give them I know that they came from the supplier.
