Derwent Academy Twin-Tip Markers are water-based with a brush and fine tip, giving you the flexibility to do stylised, detailed work or apply lots of colour to your page quickly. The brush tip creates both thick and thin lines with one stroke. The fine tip has a broad edge and fine point for maximum control. Explore a wide range of techniques such as stippling, crosshatch, layering, and blending. Apply light colours to your paper first to avoid dark ink transfer to the tips of other markers. Only apply as much pressure as you need to avoid damaging the tip of your marker.
