Metal charms for a crazy charm bracelet

I just can't seem to get enough charms! Send 10 charms to your partner and then get 10 back. When you get them, you can stick them on a charm bracelet or your key chain ...or your cat's collar - go nuts. Please only metal \m/ charms for this one, and no more than 2 of each kind.
Any size and sender's choice so you can start gathering these now.

These one is United States only because I need a break form customs forms and cranky postal workers. Next time, everyone, next time... If anyone wants to set up an international swap or another regional one, go for it. you have to write your own puns, though.

Please communicate with your partner before you rate them a one. Do not commit to this if you cannot send on time. Anyone with recent bad ratings or looking shifty-eyed and hiding sketchy past swaps under a bunch of electronic swaps will have to talk to me before the partners are assigned.
