Series 7185 and 7785 feature extremely resistant synthetic fibers, made especially for painting with thicker colors such as acrylics, oils and water-mixable oils. Constructed with 5 different diameters of extra strong synthetic bristle; thicker fibers placed on the outside work with inner fibers to trap and hold color for higher absorption and even distribution. These brushes feature hexagonal handles that prevent the brush from rolling away and the hand from getting tired during painting.

Brushes included are Series 7785 (round) in sizes 1, 2, 6 and Series 7185 (flat) in sizes 2, 4, 6, 8, 10, 12, 16. Recommended age 2+ years
