Hydrus - 15ml [1/2 oz] - Ultramarine Blue

Dr. Ph. Martin's Hydrus Fine Art Watercolour is a transparent, concentrated liquid watercolour with excellent lightfastness and archival quality. Made from the finest artist quality pigments, this product brings the same vibrancy and permanency of traditional watercolours. 
The colours can be mixed together without reducing the transparency and luminosity of the paint. The opaque white can be mixed with other colours to produce a fine gouache. 
It's suitable for brush, pen, calligraphy, technical and fountain pens and airbrush. 

Available as individual 15ml bottles and in sets.
