old clay chips. I had a very bad experience with a mail delivery yesterday. A chip I had been anxiously been waiting for arrived only to find it came in three pieces. It was in a plain envelope. The post office must have some mean machinery. PLEEEEEASE! use a padded envelope with old clay chips. They are fragile. And, as luck would have it with these old chips, there is never an extra. I got my money back but, I wanted the chip not the money. I was able to scan the pieces and Photoshop back together a whole chip for my file. See the extra link below to see the reconstructed chip. I guess I'll keep the pieces just to prove the variation does exist.
