This is a postcard commemorating the 5th anniversary of "Stpri." I think it was a non-sale item given away at Animate. It's quite old! It was stored in a clear file. There are no scratches on the front or back. ☆ Search terms (honorifics omitted): Stpri, StrawberryPrince, Riinu-kun, Riinu, Satomi-kun, Satomi, Colon-kun, Colon, Root-kun, Root-chan, Root, Jel-kun, Jel, Nanamori.-kun, Na-kun, Nanamori, Anniversary, postcard, Animate, limited edition, not for sale, bromide, 5th anniversary, old
