Dry-erase sheets are a convenient, innovative solution for quick notetaking. These disposable sheets cling to the wall or other interior flat surface like a flipchart page, but can be written on with Quartet dry-erase marker. Dry-erase ink easily wipes off to make updates as you work through a project. You can also use permanent marker depending upon your presentation need. A static charge keeps the dry-erase sheets firmly in place, even on the wall, while you write. Dry-erase sheets come on a 40 foot roll and tear off into fifteen sheets. Perforated roll enables you to easily tear off in 31 1/2" increments creating 24" x 31 1/2" sheets. Anywhere sheets are made for short-term projects: tear off, cling, write and toss away after a few days. Carton serves as a sheet dispenser. Dry-erase sheets are not designed for long-term use. After an extended period of time the Quartet dry-erase marker will permanently stain the paper.
