## Summary description

PENTEL C505-3H replacement leads for mechanical pencils, 0.5 mm diameter, hardness 3H and black writing. Each tube contains 12 leads suitable for precise technical drawing, fine-line writing and note-taking. Compatible with 0.5 mm Pentel and other standard mechanical pencils requiring 0.5 mm leads.

## Long description

PENTEL C505-3H replacement leads are 0.5 mm diameter mechanical pencil refills with a firm 3H hardness grade and black pigment. Supplied in a compact tube containing 12 leads, these refills are designed for precise technical drawing, fine-line writing and detailed note-taking. They are compatible with Pentel 0.5 mm mechanical pencils and other standard pencils that accept 0.5 mm leads.
Advantages
The 3H hardness provides a harder, lighter line suitable for drafting and situations where reduced smudging and fine detail are required. The hi-polymer composition increases resistance to breakage compared with traditional leads, maintaining consistent line width without the need for sharpening. The compact tube protects spare leads and makes storage and transport convenient.
Suitable for
Technical drawing and drafting
Architectural and engineering sketches
Fine-line note-taking and annotations
Graphing and diagram work
Students and professionals needing consistent, hard leads
Key specifications

How to use
Open the plastic tube and remove a single lead. Insert the 0.5 mm lead into the mechanical pencil according to the pencil manufacturer’s instructions. Advance the lead in small increments to achieve the desired line length; replace with a new lead when wear reduces line quality. Store spare leads in the original tube to protect them from breakage and dust.
Usage recommendations
For precise technical work, use light pressure and a consistent grip to preserve the 3H lead and maintain accurate, fine lines. Avoid excessive force when extending the lead to reduce risk of breakage.
