You've got a project that needs clean lines that actually stay put — on paper, fabric, wood, or even ceramic. The Derwent Inktense Outliner 2400 handles all of it. Use it dry for smooth, controlled linework. Add water and it shifts into a vibrant ink that dries permanent. Layer it, blend it, build it up without the lines lifting or smearing. Soft texture, highly blendable, and it holds its mark on surfaces where most inks give up. One pencil, four surfaces, zero fuss. Add to cart and get your next piece moving
