This was a Grand Jump magazine supplement. It's unopened, but slightly bent as shown in the photos. It's not creased, so I think it can be corrected. If there are any Rokudenashi Blues fans or Masanori Morita fans out there, I would be happy if you would consider purchasing it. - Size: B5 size Please note that it may be sold on another flea market site, so please forgive me if it sells there first. Thank you for looking.
