Ruling 27-9 mm lined, edge to the left and right. The high-quality paper allows the calligraphic effect, thanks to the silky smooth surface. It can be described by both sides, without the ink by punching on the back. The envelope is stable and robust, so that the volume even still looks still good after prolonged use. Light stains can simply be wiped with a damp cloth. The name field on the front of the booklet can be written in ink, without the writing blurring. The rounded corners prevent the emergence of donkey ears and let the notebook look neat and tidy.
