Because the bristles of the da Vinci Maestro2 Spalter Wide Flat-705525 brush are hand picked, an artist is assured that the stiffest ones are removed. Doing so allows the bristles to flag better at the tips so the paint is held on the brush better. This gives the artist a great deal of control over the depth of color that is applied. Using the extra wide head of this brush, along with the 12 inch, two-toned handle, gives the artist the perfect tool to use for applying grounds or for painting on a large scale. Brass ferrules that are nickel-plated and seamless help ensure the durability of this brush. The following sizes are available: 25, 30, 40, 50, 60, 80 and 100.
