You want colour that actually sticks. Not a wash-out after one raindrop, not a pencil that smears across a student's thumb. Derwent Inktense Dark Aquamarine 1210 gives you both worlds. Draw it dry for soft, blendable coverage. Add water and it locks in as permanent ink. No fixing spray, no waiting for it to set. Works on paper, ceramic, wood, and fabric — so one pencil covers the art room, the craft table, and that mug you've been meaning to personalise. 36 in stock now, ships from our warehouse the same week
