We often face a problem: the book edge angle is easy to fold or roll up, especially being put in the bag, or leaning against the shelves. Although the ordinary clip can nip a book, it is difficult to place and carry with us for the inharmonious book edge sticks the small side door. However if the clip is cut along the 45-degree angle , it can not only clamp the book, but also be smoothly placed. Of course, it also can be used as an ordinary clip.
