Grumbacher's signature line of professional oil and acrylic brushes are made of Chungking hog bristle. Natural flags and interlocked construction preserve the natural curve of the bristle.
Every Gainsborough brush is handmade to ensure a high level of quality. Each one incorporates a nickel ferrule and a long wooden handle.
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.
