Sakurazaka46 Oshimen Penlight Aiki Taniguchi - Model Name: Penlight - Brand: Sakamichi Series Purchased from the official website. Used a few times a year. There are scratches on the surface of the light-emitting part, although they are not visible in the photos. The light itself works without any problems. The strap has not been used. There was no rust found on the battery compartment. I will put it in the included case and ship it with simple packaging. Thank you for looking.
