All Wise Owl premier brushes are made with premium synthetic filaments which have gone through extensive processing in order to maximize paint pickup and release, durability of brush, and sharpness of tips. The filaments are bonded onto the ferrule with an epoxy to ensure there is no filament loss when painting. All of the handles are stained.
All brush filaments go through a tipping and flagging process. Tipping sharpens the tips of the filament for precise edging, while flagging creates micro split-ends on the tips of the filaments to reduce brush streaks and to increase surface area for paint pickup on head of filament.
