Real Techniques PowderBlue Collection: “FauxBleu™ Technology engineered to layer powders evenly for a soft, flawless finish. Known for its fine filaments, luxurious softness, and flawless powder application, blue squirrel hair is the one of the rarest and softest bristles used in prestige makeup brushes. Our FauxBleu™ Technology uses synthetic bristles engineered to perform as well as blue squirrel hair.” These sound amazing, cruelty-free and of the same high quality as the legendary Russian Blue Squirrel brushes used by top watercolour and gouache painters in preference to sable.
