Van Gogh water colours are rated as a student and artist level paint range. They feature brilliant, transparent, and intense colours with high tinting strength. Most colours are rated with the highest degree of lightfastness +++ (100+ years under museum conditions) with a few colours rated just one step below at ++ (25-100 years under museum conditions). Thanks to the purity and uniform viscosity, these water colours are easy to work with and easy to mix. Proudly produced in Holland with stringent quality control for a consistent experience with every purchase. This 24-half pan water colour set is packed in a plastic pocketbox, and also includes a round synthetic hair brush (size 6) and a sponge.
