This is an acrylic keyholder of Satomi-kun from Sutomemo 5. I used it a few times for displays, but there are no noticeable stains. I threw away the outer packaging, so I can't include it. I stored it in a dark place, but since it was stored by a private individual, please refrain from purchasing if you are sensitive to such things.
