About this item

The wiping surface is made of double-layer knitted cloth with a thin sponge sandwiched in the middle, offering superior water and dust absorption compared to ordinary felt. Each eraser measures 4×6 inches (approximately 10×15 cm), and both sides are reversible; simply flip it over when one side is dirty. The back panel is made of plastic and incorporates four round magnets, providing a total magnetic force of approximately 800 grams. Suitable for chalkboards, blackboards, and whiteboard markers. The cloth is machine washable and hand washable, and will not deform after repeated use. Ideal for large whiteboards in classrooms, whiteboards for conference rooms, and whiteboards in factories and workshops.
