What does a 4B Art pencil do?

A 4B art pencil is a soft lead pencil that produces darker and richer lines compared to harder pencils. The "B" designation indicates that it has a softer lead, which allows for smoother shading and bolder strokes, making it ideal for sketching and drawing. Artists often use 4B pencils for creating detailed illustrations, as they can easily blend and produce varying degrees of darkness.
