This item has been stored for a long time. The parts themselves aren't small, and the glass (or similar material) gives it a cool and cute appearance. The clasp is marked with "PAT2007." I don't know the details, but it seems to indicate a patent. It looks clean in the photos, but there is some cloudiness upon closer inspection. It's likely unnoticeable during normal use, but I wanted to mention it. I hope someone will like it. I am not accepting price negotiations.
