Derwent Inktense Block – Iron Blue (0840) Water-Soluble Art Block

Pencils are great for detail. They're not so great when you need a full-page wash without stopping to re-sharpen. The Derwent Inktense Iron Blue block covers that gap. Lay it on dry for textured, expressive marks, or hit it with water and watch it open into a translucent, ink-like wash. One tool, two techniques, zero mess on the desk

• Water-soluble block for broad, even colour coverage
• Add water to create translucent, ink-like effects
• Pairs the pigment of Inktense pencils with block-format freedom
• Iron Blue (0840) – cool, steel-toned blue for depth and shadow
• Ideal for expressive marks and specialty drawing projects
