I just bought the whole box of Sailor Moon blind bag keychains from my local Five Below. The manager was nice enough to leave me a voicemail message saying that they got them in. They even let me take home the box.
I was at work today just stocking stuff and we got a bunch of bags of little cheap Japanese toys. In one was a "Little Charm Sailor Moon 3" a small little jewelry mirror with a real tiny green stone. Unfortunately I couldn't stop for a pic in the rush but it seemed official enough.
