"Every Expression short-handled brush is uniquely constructed with a combination of different types and diameters of synthetic fiber, resulting in a smooth, soft feel with great resiliency, snap, and color-holding ability. The brush fiber is hand-shaped, then tied, glued, and hand-crimped into seamless, 22-karat gold-plated ferrules. Every beech wood handle receives five coats of matte, stain-resistant turquoise lacquer. Because they're generously sized and perfectly balanced, the handles also alleviate hand and finger fatigue during long painting sessions. Originally designed for crafters and tole painters, Expression brushes are also ideal for fine art applications. Brush sizes - The length and width of a brush of a given shape and size may vary by manufacturer as brush sizes are not standardized. Since fine art brushes are handmade, expect some variation even among brushes from within a single brush line.
