Albrecht Dürer Watercolor Markers contain water-based ink with high pigmentation and lightfastness. They feature two nibs, a brush nib and a 1-2mm bullet tip to offer flexibility. The brush nib allows various strokes of thickness, and the bullet tip is perfect for sharp fine lines and detailed work. With a rollaway stop-cap, the watercolor markers are the perfect companion for on-the-go art. A great amount of color range can be achieved – the amount of water you apply decides the degree of lightening, while darker colors come from adding black or grey, and also the respective complementary color.
