Using the canonical form, I made a key chain (polished) and a pendant (gold steel). The steel came out amazingly well for jewelry! I did not expect that. Much nicer in real life than the photo shows. In the store, I have since scaled down the key chain by 33% to make it cheaper and less out-sized.. This one feels great in the hand (and makes the keys easy to find!) but is a little large for my taste. The smaller size should be perfect and make for great stocking stuffers. I'm thinking in steel. 19.99. Plastic for 5.99.
