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.
