B43M BUREAU ACCESSORIES NOT OTHERWISE PROVIDED FOR (stapling devices B25C5/00; devices for temporarily attaching sheets together B42F)
Description
B43M covers miscellaneous office and desk accessories that do not fit within more specific bureau accessory classifications. This includes items such as pen holders, desk organizers, paper clips, erasers, correction devices, and similar desk-related items used in conjunction with writing instruments or document handling. The classification serves as a residual category for bureau accessories where no specialized subclass is available, complementing the more defined categories within B43 (writing implements and related office equipment). Articles classified here are typically non-powered, small office supplies intended for clerical or administrative work environments.
