Notebooks
A notebook is a stationery in which multiple sheets of bound paper are bound together with a cover in the form of a spring-like ring or glue, etc. It is useful for recording sentences and figures with writing implements, etc. and is used in every type of situation. There are various types of paper types, such as ruled lines, grids, vertical rules, plain colors, etc. and the width of the ruled lines and the size of the grids differ, so it is necessary to select them according to the application. In addition, the loose leaf that can be used by binding to a dedicated binder has multiple holes on one side, and it is possible to replace or add pages, with the number of sheets that can be stored varying depending on the type of binder. There are many notebook sizes, with most being A4 and B5 sizes, but there are also small palm-sized types that can be carried, types that are easy to separate and are convenient as memo paper, etc.
