Combining the intensity of pen and ink with the versatility of watercolour, this set of Inktense Pans from Derwent includes 12 complimentary colours, a refillable reservoir brush & miniature sponge. Ideal for working in the field or saving space in your collection, the lightweight, compact & convenient storage case even doubles as a segmented mixing palette. With their high concentrations of pigment, they produce strong, vivid tones that can be diluted with water for a translucent ink-like effect. Once dry, these washes are permanent & able to be layered or worked over without fear of affecting the previous application. Suitable for a range of surfaces and applications including paper, card, canvas, ceramic or wood, they're even ideal for fabrics such as silk or cotton.
