The design of the leather organizer can be divided into three types in the simplest way:
1) Zipper multifunction leather filofax, that is, the zipper multifunction manual we usually see. The advantages of this kind of organizer are as follows: since the zipper is closed, the small things we put in the folio will not fall off;
2) No zipper leather organizer, namely our normal universal manual, which is divided into hasp (buckle) or no hasp (buckle);
3) Calculator leather planner, that is, the multi-functional notebook is equipped with a small calculator which is easy to use;
