Abstract
A method of reusing a notebook provides a notebook having a synthetic-paper page. The method also provides a thermochromic ink pen which, when used to write on the synthetic paper page, leaves thermochromic ink markings. The method further provides a moisture carrier configured to have a liquid diffused therein. The moisture carrier is configured to erase the thermochromic ink markings from the synthetic-paper page by contacting the thermochromic ink markings when the moisture carrier is moist. The method then writes with thermochromic ink on at least a portion of the synthetic-paper page. Liquid is diffused in the moisture carrier, and the portion of the synthetic-paper page having the thermochromic ink is wiped with the moist moisture carrier, such that the thermochromic ink is erased from the synthetic-paper page.
