Holbein Artist's Watercolour is a European style transparent watercolour which also preserves the brush handling qualities inherent in traditional Japanese watercolour techniques. It may be re-wetted easily like a pan colour. For this reason Holbein does not produce watercolours in pan form, but allows artists to create their own selection. Fill the wells of a suitable palette with the desired colour selection. Permit to dry, the wet the colour when needed. Holbein offers a 108-colour range of moist transparent watercolour in both 5 ml and 15 ml tubes.
