Derwent Lightfast Pencil – Sapphire

You want a blue that reads as blue. Not the muddy, shifted tone you get from a pencil that's been sitting in a drawer for eighteen months. The Derwent Lightfast pencil in Sapphire keeps its colour locked in for up to 100 years under museum conditions. The core is opaque and dense, so one clean stroke does the work of three. Layer it over a grey for depth or lay it flat for a sky that actually looks like a sky. Detail holds. Tone stays true. You pick the shade once and trust it to sit there

• Colour stability rated for up to 100 years under museum conditions
• Opaque, dense core for clean single-stroke coverage
