What are pencil leads and when do you need them?
Pencil leads are replaceable graphite cores for mechanical pencils. You need them when the leads in your mechanical pencil run out or break. These Mars micro carbon leads from STAEDTLER are specially developed for precision work where you need a constant line width of 0.5 mm.

Why 0.5 mm is the right choice
The 0.5 mm thickness offers the ideal balance between precision and durability. This thickness is thin enough for detailed drawing, technical sketches and accurate notes, yet sturdy enough not to break constantly during normal use. It is the most commonly used mechanical pencil lead thickness for general office and study applications.

What the 2B hardness grade means
The 2B hardness grade stands for a relatively soft graphite composition. This means the leads produce darker, richer lines than harder variants such as H or HB. Soft leads like 2B are ideal for artistic work, shading and situations where you want a clearly visible, dark line. However, they wear down more quickly than harder leads.

Practical storage tip for optimal quality
The 12 leads are supplied in a handy lead box that protects your leads from breakage and dirt. Always keep the box dry and avoid extreme temperatures. Before use, check that your mechanical pencil is suitable for 0.5 mm leads - this is usually stated on the pencil. The STAEDTLER reference code 250 05-2B helps you order identical replacement leads.
