The Aquatec brush is a practical choice for thick and thin applications in oil or acrylic. Interlon is a soft synthetic fiber which is dark brown in colour. The filament is smooth enough to control fluid acrylics and oil glazes. The brush construction is full-bodied and provides firm control over thicker colour applications.
Flats, characterized by their flat ferrule and long, squared-off head, make long fluid strokes and can be used to create a sharp edge. Their longer heads hold more paint for laying out larger areas of colour.
