Mechanical pencil Staedtler 777, 0.5 mm, B lead, blue body

The Staedtler 777 mechanical pencil with 0.5 mm B lead provides consistent line quality for writing, sketching and technical drawing. Its refillable mechanism and compact blue body make it suitable for everyday use by students, designers and professionals. The B-grade graphite delivers darker, softer strokes compared with harder leads, enabling clear, legible notes and richer tonal sketching while maintaining fine control through the 0.5 mm tip.

Advantages

The pencil combines a narrow 0.5 mm lead diameter with a B hardness to produce darker lines without sacrificing precision. Its mechanical design ensures continuous use without sharpening, and the durable body offers reliable handling during extended tasks. Refillable leads reduce waste and allow consistent performance over time, while the lightweight construction supports long writing or drawing sessions with minimal hand fatigue.

Suitable for

• Everyday writing and note-taking for students and office use
• Sketching and tonal studies for artists and illustrators
• Technical drawing and drafting that require precise 0.5 mm lines
• Annotating documents and marking drafts where darker lines are preferred

Key specifications

• Lead diameter: 0.5 mm
• Lead grade: B (soft, darker strokes)
• Body color: blue
• Mechanism: mechanical, refillable lead system
• Typical applications: writing, sketching, technical drawing

How to use

Load the pencil with standard 0.5 mm leads by opening the refill compartment according to the pencil's mechanism. Advance the lead gently using the push mechanism to expose a short, stable length for precise lines. Apply light to moderate pressure to avoid lead breakage; increase pressure slightly for richer, darker marks when needed. Replace spent leads as required and store the pencil horizontally or upright with the tip protected to preserve the lead integrity.

Usage recommendations

For best results use high-quality 0.5 mm B leads compatible with standard mechanical pencils. When drawing fine details, keep the exposed lead length short (around 2–3 mm). Use a soft eraser for corrections to preserve paper surface. Avoid excessive force on the tip to reduce the risk of lead breakage.
