Sailor Moon locket buttons I made! Usagi's locket from Sailor Moon R, specifically. I sell them on my etsy! [link]
which is why I have a whole pile of them.
I came up with the idea to have the design show up on metal, instead of printed opaque, they look a lot cooler this way. They're 2.25" in size, about the size of the top of a pop can. Pins really great to clothes and handbags, my purse is so extra-cool now.
