Siberian Mountain Weasel
The Siberian Mountain Weasel (Mustela sibirica), is also known as the Siberian Weasel, Kolinsky or Himalayan Weasel. It is a rust colored relative of the weasel family. Siberian weasel fur makes the finest water color or oil paint brushes and is especially sought after by artists. The so-called kolinsky sable-hair brush is produced using the winter fur of the male Siberian weasel, not sable.
