Box of 6 Junior Da Vinci brushes Stretchy gold synthetic fibers in a stable, almost indestructible brush head, with a really fine tip for painting, and best of all: No annoying hair loss, even after rough use! A polished aluminum ferrule that does not rust. The handles have subtle, hexagonal flat sides to prevent "roll" (an important step in keeping tables, chairs, floors, and clothing clean). The set contains 6 brushes: 3 round brushes for detail and precision painting, and 3 brushes plans for work in large areas. (Series 303 numbers 1, 4, 8 and Series 304 numbers 4, 6, 10)
