Synthetic hair long bristle cat's tongue brush, ideal for working on the first layers or on plastered backgrounds.
The Ivory is synthetic bristle at its finest, a cross between the feel of nylon and hog bristle.
I use these types of brushes a lot for the first layers or when I work on pastured backgrounds, because of their oval shape, their stiffness and the length of their bristles, they seem appropriate to me, besides that they last a long time and are inexpensive.
