To use this book folio, start by placing your favorite TTRPG sourcebook inside. You can slide the back cover of the sourcebook into the back pocket for quick access. Use the pocket in the canvas cover to store important notes or maps. For character sheets and notes, write on the wet/dry - erase compatible pages and simply wipe them clean when needed. Insert your standard size spell cards into the 9 - pocket pages. Keep your writing tools in the elastic loop. As for maintenance, avoid getting the leatherette cover wet for long periods as it may damage the material. If the pages get dirty, gently wipe them with a soft, dry cloth. When not in use, store the folio in a cool, dry place to prevent warping or damage.
