A Velcro tape was attached as a device for attaching and detaching the (Fig. 3). The lower part of the blackboard eraser (Figure 2) consists of a sponge to provide elasticity to the friction part and cloth to cover it. The upper part of the blackboard eraser can be placed over the lower part like a box lid, and the friction part cover can be stored inside.
