Erasers and eraser tops are sold in small packs and bulk counts. Quantities shown range from 2–3 up to 25, with common pack sizes including 4, 6, 12, and 24.
For whiteboards: magnetic dry-erase erasers with felt or plush (or microfiber) cleaning surfaces. For pencil use: cap-style erasers and retractable rubber erasers designed to remove pencil marks.
Common features include clickable retractable buttons (pen-like mechanisms), clips for attaching to notebooks, and magnetic backings for sticking to whiteboards—these make use and storage easier.
Erasers and novelty eraser tops are marketed for students, teachers, classrooms, and home learning. Some novelty or mini erasers are labeled suitable for children ages four and up.
Some retractable novelty erasers include a removable push button and instructions to insert a refill eraser from the top, indicating they accept replacement eraser pieces.
Whiteboard erasers typically use soft felt, soft fabric, or microfiber cleaning surfaces, which are gentle on boards and effective at removing marker residue.
