This is a set of 10 Gegege no Nazo clear files, 5 each of A and B. They are already in OPP bags, so unless otherwise requested, I will ship them in an envelope with cardboard reinforcement on one side only. Please feel free to comment if you have any questions. I made a mistake when purchasing and bought 10 of each, so I'm selling them for less than the retail price. Retail price is 440 yen. I accidentally bought 10 of each, so I can add up to 3 more of each if you'd like. Please comment if you're interested.
