Rollbahn L size file pockets and thick paper. There are 20 file pockets. There are 4 sheets of thick paper. How about for customization? These are disassembled from a used Rollbahn notebook. I don't think there are any noticeable creases. Some of the thick paper may have minor scuffs. These will be sent in a simple package, directly into a Yu-Packet Post Mini with the file pockets sandwiched by the thick paper.
