Crafted with care and shaped by hand, this oil and acrylic brush has a flexible hair bundle resistant to wear. The flexibility of the golden synthetic hair bundle makes this brush especially great for acrylic painting, since acrylic colours are normally used in a more liquified consistency. The brushes have a flat (Gussow) shaped hair bundle to create sharp edges and straight lines. The hair bundle widths of the brushes included are 3.5mm, 4.3mm and 5.3mm
