Within Dynasty's line of brushes, this sable is a natural hair brush created using hair from the Mongolian sable, doing so in a sustainable way without harm to the animal or environment. FM Brush supports the fight against animal testing and uses wood for the handles in all brushes from wood reforestation programs.
If you are looking for a brush with natural hair, soft and suitable for watercolor, gouache or casein and oil, this is your brush. These brushes are all long handled, intended for the painter working on an easel or en plein air. They work ideally with buttery oil paints or detailed watercolors, coming in brights, rounds, angles, fans and filberts. I have found that the fan brush in particular is ideal for soft blending, similar to using a light badger hair brush.
