When do you use lead refills?
Lead refills are indispensable additions to your mechanical pencil when the original lead runs out. You need them for technical drawing, detailed work, architectural sketches or precise writing where a consistent line width is essential.

Why choose a 0.3 mm diameter?
The 0.3 mm diameter produces very fine, precise lines that are perfect for detailed work. These thin leads are ideal when you need to write small letters, make technical drawings or work on projects where accuracy is paramount. The narrow line gives you more control than thicker alternatives.

What does the HB grade mean?
HB stands for the hardness grade of the graphite and offers a balanced combination of hardness and softness. This standard lead produces dark, clearly visible lines without exerting too much pressure on the paper. HB is the most versatile choice for general use, from taking notes to sketching.

Practical tip for compatibility
These Pentel leads have the reference code 300-HB and are specifically designed for Pentel mechanical pencils that accept 0.3 mm leads. Always check whether your pencil is suitable for this diameter before purchasing the leads. With 12 pieces per pack, you have sufficient stock for long-term use.
