Ruby Satin® long and short handle brushes are made with quality synthetic filaments that have the shape and feel of interlocked bristles. They have a precise snap and excellent color control, no matter if you are using extra heavy bodied acrylics, oils or water-mixable oils. A seamless, nickel-plated brass ferrule and an epoxy seal offer additional protection to the filaments so you can paint with confidence on wood, canvas, and tough surfaces.
