Manga Manuscript Paper (Opened) Paper Size: A4 For B5 Doujinshi 22 sheets Instant purchase OK I bought this over 10 years ago and used about half of it. After that, I stored it in a dark place. There may be some age-related deterioration. Please refrain from purchasing if you are nervous about this, as it has been stored by a private individual. Will reinforce both sides with cardboard and package to be waterproof.
