Outlet-books and red line
red line(Secondhand books)
A red line is in the upper part or the lower part.

A photograph is a sample.

It is not by the actual thing.

A publishing company is the book which lowered and resold the price.

A preservation state is good like a new article.

Outlet-books
If red line is removed, it is the same as that of brand-new.

They are not secondhand books.
