OwO This one's my favorite. I'd keep it to wear if I didn't already have lots of cool things to wear. XD

A little rusty diary key from sometime prior to the 1950s... a little steel thing. While I cleaned it up a bit, I didn't want to remove all the rust since I like that look. X3 So I kept it and gave it some deep iron ore purple beads and such to complement it.

For sale! (Though I'd keep it if I could X3c)
