This refill is designed for standard 0.7mm mechanical pencils that use 0.7mm leads. Check your pencil model’s specification to confirm compatibility with 0.7mm leads.

1) Remove the pencil cap and slide out the old lead. 2) Insert a new 0.7mm HB lead into the pencil’s tip chamber. 3) Advance the lead slightly to ensure it’s feeding correctly. 4) Replace the cap and test by writing a short line to confirm smooth feeding.

The lead core is designed to be more durable to resist breakage during normal writing and pressure. This helps reduce interruptions during note-taking or drafting when you apply a bit more pressure or write quickly.

Ideal for students, office work, and drafting. It provides reliable, smooth lines for writing, outlining, and light sketching in everyday tasks.

Store the refills in a cool, dry place away from excessive pressure. Keep the leads in their packaging until ready to use and avoid exposing them to moisture or heavy impact that can cause chipping.

Yes. This is a graphite-based mechanical pencil refill meant for benign use in educational and office settings. It’s designed for routine writing tasks and does not involve hazardous materials beyond standard graphite particles.
