Mechanical pencil lead refills Lyra model WIKR-1009101, B grade graphite, 0.5 mm

Lyra mechanical pencil lead refills WIKR-1009101 are 0.5 mm B-grade graphite leads designed for smooth, dark lines in writing, sketching and technical drawing. Supplied as spare leads for compatible mechanical pencils, these refills allow fast replacement and uninterrupted work in school, office and creative environments. The B hardness delivers a softer stroke than standard HB, producing richer tone and improved shading while still maintaining sufficient strength for everyday use.

Advantages

These 0.5 mm B leads combine softness and durability to provide consistent line quality with reduced pressure, making them suitable for extended writing and sketching sessions. The uniform diameter ensures reliable feeding in most 0.5 mm mechanical pencils, while the darker graphite tone improves legibility and contrast on paper. Packs are arranged for convenient storage and quick access during lessons, meetings or drawing tasks.

Suitable for

• School writing and note-taking
• Sketching and preliminary illustrations
• Technical drawing and drafting where softer lines are required
• Everyday office use and annotation

Key specifications

• Lead diameter: 0.5 mm
• Graphite grade: B (soft, darker tone than HB)
• Compatibility: for mechanical pencils accepting 0.5 mm leads
• Typical applications: writing, sketching, shading, technical sketches

How to use

Open the refill container and insert a single lead into the loading chamber of a compatible 0.5 mm mechanical pencil according to the pencil manufacturer’s instructions. Advance the lead with normal mechanism operation and replace leads as they wear. Store spare leads in their original container to protect them from breakage and moisture.

Usage recommendations

For best results, use these B grade 0.5 mm leads for tasks that benefit from darker, softer lines such as shading, sketching and handwriting where increased contrast is required. Apply moderate pressure to avoid snapping the lead and keep spare refills in a rigid case to prevent breakage during transport.
