Self-clean board / blackboard

Self-clean board
Self-clean board

In order to avoid the disadvantages of traditional blackboard, self-clean blackboard provides a more convenient way to clean it with the inner brush in stead of the handhold ones. Meanwhile, the storage of dust inside the blackboard effectively reduces the possibility of breathing the dust into body and the pollution to environment. The blackboard surface is set around two rollers and thus can be rotated by turning the handle.
