Steampunk jewelry supplies

For this swap you will be sending your partner at least five different items that they could use in the creation of steampunk jewelry. These can include charms, bits of old jewelry, keys, gears (though if you send tiny ones send a few), industrial hardware, natural objects like fossils (only send bones if your partner is ok with it and check customs info if you're sending internationally) or anything else you can think of. Be creative here and don't be afraid to think outside the box of what could become jewelry. These supplies could be handmade, store bought, or (most likely) found objects. Be sure to package everything well enough that nothing gets ruined in the mail.
And of course, have fun!
