Most small whiteboard erasers have a soft felt or microfiber cleaning surface, a foam or printed-foam body for a light grip, and some include built-in magnets so they can stick to the board for storage.
Kid-focused novelty mini erasers are playful and sized for small hands, easy to hold, and often used as classroom rewards, to encourage students to erase, and to support group activities.
Many mini erasers are compact enough for bins, drawers, or pencil boxes; some whiteboard models include magnets so they attach to the board for quick access.
Dry-erase minis are intended for whiteboards, marker boards, lap boards, and other dry-erase surfaces such as melamine, painted steel, porcelain, and glass. Sponge-style cleaning erasers are marketed for household surfaces like walls, bathtubs, shower glass, tile, stovetops, ovens, and sneakers; some listings caution against using them on copper, polished surfaces, or wood.
