How to use

Advance the lead by pressing the push-button cap; the brass mechanism delivers controlled increments. Use the sliding sleeve to support the lead during writing and reduce breakage. If the lead becomes too short, open the push-button cap to replace or add new 0.5 mm HB leads. Use the built-in eraser for small corrections.

Recommendations

For consistent performance, use quality 0.5 mm high-polymer HB refills and store the pencil in a case or pouch to protect the metal finish. When drawing fine details, apply light pressure to minimize lead breakage despite the cushion mechanism.
