GRIGIO: a new synthetic fiber developed by da Vinci, superior to synthetic mongoose brushes. Different diameter, slightly textured fibers are finely assembled to guarantee color absorption, strength and high elasticity.

The brush handles are made from sustainable forests and feature a bordeaux, hexagonal handle that won't roll away. This set includes Series 7195 Size 4 and 8; Series 7495 Size 8 as well as Series 7795 Size 2. Synthetic, Oil, Assorted, 3 Brush Set
