Book holders are used to read heavy books so that the reader does not have to hold the book while reading. These holders are known as large book-sized panels, where the book slides in. They are large, obtrusive, heavy, and hide the cover of the book. The invention reduces the size of the device to its function and combines it with the option to be bent to any angle and does not hide the bookcover. With its design and function it can also serve as an advertising device.
