A blackboard eraser is an essential tool in classrooms, offices, and educational institutions where traditional chalkboards are still in use. It is designed to remove chalk markings efficiently, keeping the board clean and ready for continuous use. Typically, blackboard erasers are rectangular in shape and consist of a wooden or plastic handle attached to a felt or foam base. The felt or foam layer ensures smooth wiping without scratching the board surface.
Blackboard erasers are lightweight and easy to handle, making them suitable for repeated use over long periods.
