This is a Regular Size refill that uses kraft paper. An original paper is used for this notebook where both the rough texture of the kraft paper and writing suitability is achieved. The rough feeling you get from using pencils and ballpoint pens is great. Water-based pens and fountain pens also go well in a sense that it is difficult for the ink to do stains or sinks through the other side of the paper. Please use this refill freely by using it as a scrap book or as a memo. It can even be used to draw by making full use of the characteristic of kraft paper. Blank, 64 pages, Kraft paper (Saddle stitched: 2 staples) Package size: H210 x W110 x D4 mm Weight: 64g (w/o package: 62 g) Made in Japan
