How to use

Press the push-button cap to advance the 0.7 mm HB lead in small increments. Replace the lead by removing the cap and inserting new 0.7 mm high-polymer leads into the mechanism. Use the fixed lead sleeve when drawing with a ruler to maintain precise lines. The built-in eraser under the cap removes graphite marks; if worn, replace with a similar sized eraser insert.

Recommendations

For accurate technical lines, use a ruler and keep the fixed lead guidance sleeve close to the page; store the pencil horizontally to preserve the mechanism and avoid dropping to prevent damage to the metal body and internal components.
