Derwent Inktense Pencil – Iron Blue (0840)

Iron Blue sits in that sweet spot between navy and cobalt — cool, grounded, a little moody. The Derwent Inktense pencil gives you a soft, blendable dry line, then unlocks into a rich permanent ink with a drop of water. Layer it, build tone, stop when it's right. Paper, ceramic, wood, fabric. RRP $7.39. Six on the shelf and going
