The unique design of the Dynasty Urban FX brush is ideal for artists who paint on buildings, sidewalks, and other surfaces in urban settings. The strong natural bristles in these brushes work well on smooth surfaces such as concrete, but also do a great job filling cracks on brick walls and other rough surfaces. The bristles are densely packed into seamless black ferrules, delivering a tremendous amount of paint in a continuous, smooth flow. The well-balanced , brightly colored neon handles are coated with a soft-touch , non-slip lacquer for optimum feel and ease of handling in all environmental conditions.
