Derwent Retractable Mechanical With 8 Refill Battery Operated 2301931

Erasers are used for more than just providing precise media removal. An eraser is actually an artist's tool, much like a burnisher or blender.
The Derwent battery operated model will thoroughly erase the darkest graphite with ease, but you can also use it for pencil and charcoal edge cleanup, for creating crisp, erased edges within tight areas and for pulling out small detail highlights in a graphite drawings. The operating button is positioned on top of the eraser for right and lefthanded users. A favorite for artists of all levels, it includes 8 erasers and requires 2 AAA batteries (not included).
