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. This hair bundle of these brushes is cat's tongue (filbert) shaped, that unites the advantages of flat and round shaped brushes giving you great control over the paint. The hair bundle widths of the brushes included are 3.7mm, 5.0mm and 5.9mm
