How to use

Remove the push-button cap to access the built-in eraser or to load replacement leads through the rear. Press the push-button to advance the 0.5 mm lead as needed; use light, controlled presses to avoid over-advancing and breaking the lead. When drawing with a ruler, rest the fixed lead guidance sleeve against the ruler edge to maintain a consistent line while keeping the view of the page unobstructed. Replace leads with compatible 0.5 mm high-polymer leads and close the cap securely after use.

Recommendations

For best results use high-polymer 0.5 mm HB leads for a balance of dark, smudge-resistant lines and easy erasing; store the pencil in a case or horizontal position to avoid accidental damage to the sleeve and tip.
