This is a "Koi" limited edition T-shirt that was sent to only 510 winners of a lottery held when Gen Hoshino released the song "Koi"! #GenHoshino I was so happy to win and kept it carefully at home, unused and unopened, but then I started liking another artist, and only the T-shirt remained...(^^) It's a very valuable T-shirt, and I thought that there might be someone who really wanted it back then... I thought it would be a waste to keep it like this, so I decided to put it up for sale. Color: Yellow (front and back design) Size: M size Please feel free to comment if you have any questions or if you'd like to negotiate the price. (^^)
