Abstract: ABSTRACT INTEGRATED BLACKBOARD DUSTER WITH DUAL-ACCESS HOLLOW HANDLE STORAGE FOR CHALK AND PEN The present invention discloses an integrated blackboard duster assembly (100) designed to consolidate writing tool storage and board cleaning functions into a single ergonomic device. The assembly comprises a rectangular ABS polymer duster body with a high-density microfiber wiping surface (101) and a hollow handle (110) integrally molded on its top surface. The handle (110) incorporates two internally partitioned storage compartments: one accessed via a front-facing snap-fit lid (120) for pens or markers, and the other via a lateral silicone-lined slot (130) for chalk sticks. A fixed internal ABS partition (140) separates the compartments to prevent chalk dust contamination of writing instruments. All components are permanently joined through injection molding and ultrasonic welding. The device enables users to retrieve chalk or a pen and erase markings seamlessly with one hand, reducing classroom clutter and improving workflow efficiency. [
