Neef 95 Stiff Synthetic Filbert Brushes are perfect for acrylic painting particularly heavy body or structure paints. They are also excellent with solvents and oil paints. The special synthetic fibres in the bristles resist hair loss and the resilient stiff bristles interlock to snap straight back into shape even when creating points or edges, offering the user precision and control. Neef 95 Stiff Synthetic Filbert Brushes can also hold a large amount of paint whilst still maintaining a firm line with each brush stroke. The Filbert shape brush is flat but with rounded bristles. It is good for blending and creating soft rounded edges.
