Neef Series 2013 Kazan Mahogany Rigger Brush

Kazan is Neef's synthetic alternative to a natural squirrel-hair watercolour brush, offering the same absorbancy, spring and smoothness. 

A rigger is similar to a classic round-shaped brush, but with extra long, flexible bristles. It allows for superbly controlled, thin lines, with the long bristles holding more paint than a round.
