What are lead refills and when do you need them?
Lead refills are the replaceable graphite cores for mechanical pencils. You need them when the leads in your mechanical pencil run out or break during intensive writing or drawing work. These Mars micro carbon leads ensure that your mechanical pencil functions optimally again.

Why choose 0.5 mm thickness?
The 0.5 mm thickness is the most widely used standard for mechanical pencils and offers the ideal balance between precision and durability. This thickness gives you sufficient control for detailed work such as technical drawing, taking notes or mathematical calculations, without the leads breaking too quickly under normal use.

What does the HB grade mean?
HB stands for the medium degree of hardness - neither too hard nor too soft. This means you get a nice, dark line without the lead wearing down or breaking too quickly. The HB grade is perfect for everyday writing, as it gives sufficient contrast on paper while writing smoothly without applying too much pressure.

Practical tip for use
These STAEDTLER leads are compatible with all mechanical pencils that use 0.5 mm leads, regardless of the brand of your pencil. With 12 pieces in the pack, you have enough stock for long-term use. Store the leads in the supplied case to prevent breakage and make sure your mechanical pencil is clean before inserting new leads.
