Mechanical Pencil

Mechanical pencils are writing instruments that use a thin lead refill instead of traditional graphite or ink. They are commonly used in offices, schools, and other professional settings. Mechanical pencils have a cylindrical barrel that holds the lead refill, which can be advanced by either clicking a button or twisting the barrel. This eliminates the need for sharpening and provides a consistent, fine line for writing or drawing. Mechanical pencils are available in various lead sizes, such as 0.5mm, 0.7mm, and 0.9mm, allowing users to choose the thickness of the line they prefer. They are often preferred by those who require precise and neat writing, such as engineers, architects, and artists.
