This is a Hobbytech Kolinsky Sable Round Paint Brush Size 6.

When it comes to brushes, most hobbyists have heard of Kolinsky sable. Pure sable hair brushes are the first choice for artists of all types for their high moisture holding capacity, a tip that will return to a point repeatedly and for the excellent spring in the hair while applying paint. 

Ideal for many paints - including acrylic, lacquer and enamel, and on most surfaces, Kolinsky Sable brushes will last longer than many other brushes when maintained and looked after by the artist.

The size of a brush is shown by a number on the handle. Brushes can be as small as 20/0, then go up to 5/0, 000, 00, 0, 1, 2, and up. The higher the number, the bigger or wider the brush.

This pack includes 1x size 6 Kolinsky Sable round brush.
