Authentic system notebook, capable of holding 200 sheets. (Self-made refills and usage examples are shown in the latter half.) A genuine leather cover made for B7 mini loose-leaf refills from brands like Maruman and Daiso. The size is 170mm wide, 100mm long, and 30mm thick. The color is black, with a crocodile pattern. Reinforced with a lining and two layers of leather, it feels sturdy. It includes a leather pen holder and a large bookmark. This bookmark also serves as an underlay and paper holder. It makes using the loose-leaf refills even easier. One Daiso loose-leaf refill is included. You can use it like a notepad anywhere and organize it like a system notebook. "Systematization" As described below, you can systematize simple memos, transforming it into an intellectual tool like a system notebook with a wide range of uses. You don't have to stick to commercially available mini loose-leaf refills. Also, with self-made refills, you can use the paper vertically, and the metal rings won't get in the way. Self-made refills are also cheap, so you can use a large amount of disposable memo paper. (Systematization refers to treating a single memo as data, and enabling data accumulation, data modification/replacement, data insertion/overwriting, data sorting, data association, and grouping by theme, which is impossible with a notebook, and is useful for intellectual organization and production.) "Self-made Refills" As shown in the last photo, you can make mini loose-leaf refills of almost the same size using a punch from the Raffinee IO memo pad (160 sheets, 2 pads) sold at Daiso. You can also file this memo pad in the three-hole cover after writing on it. Since it's blank, it's often easier to use than those with lines. You can also do the same with B7 size memo paper. Memo pads of this size are very cheap, so you can use as many as you want.
