B43L ARTICLES FOR WRITING OR DRAWING UPON; ACCESSORIES FOR WRITING OR DRAWING (workshop equipment for marking-out work B25H7/00; teaching hand-writing or drawing G09B11/00)
Introduced: September 1968
Description
B43L covers materials and accessories used in conjunction with writing and drawing implements, rather than the implements themselves. This includes writing papers, drawing surfaces, erasers, sharpeners, ink bottles, and similar consumable or auxiliary items that support the writing and drawing process. The classification encompasses both traditional substrates (paper, parchment) and accessories that facilitate or enhance writing activities. Related implement classes such as B43K (pens and pencils) and B43M (typewriters and similar machines) are classified separately.
