The Inart Electric Eraser with 14 Refills (110699004) is a motorized eraser that rotates a small rubber tip at high speed, allowing you to erase small details more quickly and precisely than a regular eraser. Thanks to this rotating motion, it's possible to create reflections, textures, and light effects directly on works done with dry techniques, such as graphite, charcoal, or pastel, without rubbing and soiling the surrounding area. The package includes 14 refills of two different diameters and an adapter for the thinner refills, which significantly extends the life of the device before needing to buy refills separately. It works with 2 AAA batteries, not included in the package. It is suitable for those who do observational drawing, detailed illustration, or graphite portraiture, where precision in erasing is as important as the stroke itself.
