Dry-erase sheets are a convenient, innovative solution for quick note-taking. These disposable sheets cling to the wall like a flip-chart page, but can be written on with a dry-erase marker. Dry-erase ink easily wipes off to make updates as you work through a project. A static charge keeps the dry-erase sheets firmly in place on the wall while you write. Dry-erase sheets come on a 40' roll & tear off into 15 sheets. Dry-erase sheets are perfect for short-term projects. Tear off, cling, write & toss away after a few days. After an extended period of time, the dry-erase marker will permanently stain the paper.
