Pencils

Type: Pencils

1. Lead type: Pencils can have different types of lead, including standard graphite, colored, and water-soluble. Each type of lead has its own unique properties, such as hardness, color vibrancy, and ability to dissolve in water.
2. Lead grade: The lead grade of a pencil determines its hardness and darkness. Standard lead grades range from 9H (hardest and lightest) to 9B (softest and darkest), with HB being the most common medium grade.
3. Barrel material: Pencil barrels may be made of wood, plastic, or other materials. Some barrels may be coated or textured for better grip and control.
4. Eraser: Most pencils come with an attached eraser, though some may have removable erasers or no eraser at all. Erasers can vary in size and quality, with some brands offering high-quality erasers that erase cleanly and completely.
