Sure we learn by our mistakes, but we don’t have to advertise them to the world. If you make more mistakes than the tiny nub of an eraser on your pencil can handle, maybe it’s time to upgrade to an electric eraser like the above Sakura model.
Powered by two AAA batteries, this compact eraser runs spins at 12,000 RPM to quickly remove marks. Designed to be easy to control and comfortable to use, it weighs only 2.8 oz. It uses two different types of erasers: white vinyl for pencil and blue solvent for drafting ink.
Pricing for the electric eraser starts around $35 before shipping. You can pick up a 70-pack of replacement erasers for about seven or eight bucks.
