Plaza Montgomery Synthetic Mongoose Brushes are perfect for Heavy-Bodied Oils and Acrylic paint. The blend of different thickness filaments provides ideal spring and resiliency. Unlike natural hair brushes, this synthetic hair brush will remain firm when used with water-based paints. The heat shaped, toed-in edge creates precise control and the twice epoxied head and crimped handle forms a permanent bond for stability. Made to “industry standards” the interlocked bristle of Plaza Montgomery offers more brush for the money.
