This is the Seibunkan bonus for volume 15 of Toilet-bound Hanako-kun. It was originally folded into four. It's a first edition. It's officially labeled as a "paper," but it's thick cardstock, so it's not flimsy. It will be shipped via Yu-Packet Post Mini, with measures taken to prevent water damage and folding. Discounts are available for combined purchases. Unreasonable price negotiations will be blocked.
