Abstract
A writing board eraser consisting of a trough-like main body with two substantially flat end panels, a hollow handle integral and perpendicular to a longitudinal side of the main body, a soft flexible erasing pad covering at least half of an oval cylinder surrounding an axel rod connected to a rotating lever, which enables rotating the erasing pad to contact a longitudinal scraping blade attached to the internal concave surface of the trough-like main body thus removing dust which then drops into the hollow handle, which includes a threaded distal end with a mating cap for removal of accumulated dust.
