How to use
Open the plastic tube and remove a single lead with care to avoid chipping.

Advance the lead gradually while writing to maintain an even line and replace leads as they wear down. Store unused leads in the original tube to protect them from pressure and breakage.

For best results, use with mechanical pencils rated for 0.5 mm leads and avoid excessive lateral pressure to reduce the risk of breaking. When performing precise technical drawing, keep a clean eraser and ruler nearby to maintain line clarity and accuracy.
