Thank you for looking! This is a staff T-shirt from THE IDOLM@STER SideM 6thLIVE. It has not been opened from the bag and is in new, unused condition. (It may have some dust on it due to being stored in a closet for a long time. I will take it out of the original bag, put it in a new OPP bag, and ship it. Please understand.) The size is M. I am not considering a significant price reduction, but I can lower it by about 400 yen. I will fold it up small for shipping. Please feel free to ask if you have any questions.
