A clipboard includes a plate body formed to have a predetermined area to support document paper; and a clip portion extending from one comer of the plate body and fixing the document paper seated on the plate body to prevent the document paper from being separated from the plate body. The clip portion includes a second fixing member, a first fixing member extending from the second fixing member, and a third fixing member formed symmetrically with respect to a boundary surface between the second fixing member and the plate body; the second fixing member is configured to be folded with between the second fixing member and the plate body to cover the document paper; and the first fixing member is configured to be folded with respect to a boundary surface between the first fixing member and the second fixing member, so that the document paper can be fixed.

A magnetic writing book including a writing book body and a metal iron sheet with one side being provided with a backing. The writing book body includes a book back cover, a book back cover and a cylindrical permanent magnet. The backing is pasted on a wall surface or an object with non-magnetic attraction, and the magnetic writing book with adhesion on any non-metal wall surface is realized. One end of the cylindrical permanent magnet is fixedly connected with the book back cove, an other end of the cylindrical permanent magnet penetrates an upper half of each page of the writing pages.
