It can be used dry but when mixed with water the colour turns into vibrant ink. With 71 pure, vibrant colours and a non-soluble outliner, these pencils offer a diverse palette for your creative expressions, all sold separately. The round 8mm barrel provides a comfortable grip, while the wide 4mm core allows for both fine details and broad strokes. Once dry, the colours are fixed and can be layered for added depth. These pencils are particularly well-suited for fabric applications, such as silk and cotton, thanks to their permanent nature. Ensure all pigments are dissolved in water for lasting results, as any dry pigment may wash out if exposed to further water.
