This is from AP STUDIO. I purchased it here, but it was a little too big for me, so I'm selling it without wearing it. ■ Description at the time of purchase: There are almost no noticeable stains or scratches, but there is a slight yellowing on the inside of the collar if you look closely. (It's barely noticeable, but please understand this before purchasing.) ↑ I didn't notice it at all.
