Made with an innovative DuPont™ filament formulation, easy clean and long lasting. These are fixed with Hamilton's patented Thermoset™ bonding, with 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 tramlines in water-based coatings for a smoother finish. Set comprises 1x 25mm(1"), 1x 37mm(1.1/2") and 2x 50mm(2") brushes. Made in Sweden.
