    When people reads book, the read part is always folded (and further turned back) and the part not read yet is also folded in sometimes, especially for a thick look. This invented slipcase can sleeve the read part (sometimes also including a page not being read yet) or sleeve the part not read yet so as to make it not be folded (and further turned tack), and thus, it is convenient for reading book.
