Geyer has multiple erasers that can be helpful in the classroom or office. The student erasers are small enough for younger students to hold comfortably. They come in a 12 and 24 class pack. The felt eraser and Expo eraser are slightly bigger and work with a lapboard or the room's whiteboard/chalkboard. A better resource for the large whiteboard/chalkboard are the jumbo and large erasers. Their size makes it possible to erase large amounts of work in a few motions. The magnetic eraser is also nice to have for the room's board because it can stick without falling or being knocked off a tray. The glue stick, classic pink eraser, and pencil cap erasers are essential to have at any desk.
