I used ten sheets earlier, and it is now cheaper to use because it is cheaper. It is an indispensable item for document submission in the company and document management in the ring file. There is an opinion that it is better not to protrude from the binder by making it slightly narrower than those of other companies. Because it is narrow, there is no inconvenience in handling documents. Originally, in one pocket, it is not something to put in something to be cut off.
