Technical Pencil Lead Grand 4B — pack of 12 for mechanical pencils

Pack of 12 Grand 4B technical pencil leads designed for use in mechanical pencils. Each 4B lead delivers a soft, dark line with high contrast, suitable for sketching, shading, technical drawing and general writing. The leads are intended for mechanical pencils that accept standard 4B refill leads and provide consistent laydown and smooth performance for repeated use.

Advantages

These Grand 4B leads produce deep, even tones with low pressure thanks to their soft graphite composition, making them well suited to tonal work and quick sketching. The uniform core formulation reduces breakage during typical mechanical pencil use and maintains a consistent width and darkness across the pack. Their compatibility with common mechanical pencil sizes ensures easy replacement and minimal downtime for artists, designers and students.

Suitable for

• Sketching and freehand drawing
• Shading and tonal studies
• Technical drawing where a darker line is required
• General writing and note-taking with a soft stroke
• Art classes, design studios and office use

Key specifications

• Hardness: 4B (soft, dark graphite)
• Pack quantity: 12 leads
• Intended use: refill leads for mechanical pencils
• Line quality: soft, high-contrast strokes suitable for shading
• Break resistance: formulated for reduced breakage in standard mechanical pencils

How to use

Load a single 4B lead into a compatible mechanical pencil following the pencil manufacturer's instructions. Apply gentle, even pressure when drawing or writing to avoid excessive breakage; the soft 4B core is designed to deliver dark marks with less force. When the lead shortens, advance or replace it as needed to maintain consistent line quality. Use an appropriate eraser for soft graphite when correcting marks.

Usage recommendations

For longer lead life and fewer breaks, use these 4B leads in mechanical pencils with a well-aligned clutch mechanism and avoid applying sharp lateral pressure. Store the pack in a dry place and keep spare leads in their original sleeve until use to preserve integrity.
