Setup, Compatibility & Care
No assembly is required for this product; it is ready to use immediately upon unboxing. The Muji Eraser is compatible with all standard graphite pencils ranging from 2H to 6B hardness. To maintain the life of your eraser, keep it in a cool, dry place away from direct sunlight or extreme heat, which can cause the material to harden or become brittle. If the surface becomes saturated with graphite over time, rub the eraser firmly against a clean piece of scrap paper to "reset" the surface and restore its erasing efficiency.
