Made with an innovative DuPont™ filament formulation, easy clean and long lasting. Fixed with Hamilton's patented Thermoset™ bonding, special resin-bond system to minimise filament loss. Unique deep-flagging technology simulates natural 'split' bristles for the best paint pick-up and better paint spread. The filament tips are ground and sanded for the finest finish and increased paint flow. This treatment helps to reduce tram-lines in water-based coatings for a smoother finish. Forest Stewardship Council (FSC) certified wooden handles from environmentally managed sources. Made in the UK.
