Princeton's synthetic mongoose is comparable to the original’s quality, yet more durable and affordable. Synthetic mongoose performs beautifully in all viscosities of oil paint. It is stiffer than sable but softer than hog bristle, with a tapered point excellent for painting detailed, controlled lines. The synthetic fibers offer greater durability than natural hair.Details:Round LinerSize 8Synthetic mongoose filamentSeamless metal ferruleComfortable touch handleMedium to firm stiffnessFor use with oil and acrylic paints
