Derwent Graphic Technical Pencil Tin, 12 Pencils

It means the set covers a spectrum from extra hard to soft graphite. Harder grades create light construction lines and precise detail, while softer grades produce darker tones and shading. You get a full range for both line work and tonal contrasts.

The pencils are engineered with smooth graphite cores that deliver fine, even lines with minimal tooth or texture. This ensures consistent line quality across grades, which is essential for technical illustration and architectural drafts.

The 12 pencils come in a compact tin case that protects the leads, keeps the pencils organized, and makes it easy to transport between studio, site, or classroom—great for on-the-go projects.

Technical illustration, architectural drafting, product design sketches, CAD pre-sketching, schematic diagrams, and any work requiring precise lines and controlled tonal range.

Start with mid-range grades (such as HB to 2H) for construction or light construction lines. Use harder grades (H–2H) for lighter lines and precise outlines, and switch to softer grades (B–2B) for darker lines and shading as needed.

This 12-grade set offers a full hard-to-soft range in a single tin with a durable, protective case, making it well-suited for professional work. Other on-site options include:
