Gustave Bernadel Rosin is great for advanced students to professional players. French-made Gustave Bernadel rosin creates a nice, smooth feel on the violin, viola and cello. It is a light colored medium sticky rosin for smooth playing and a clean, bright tone. Bernadel Rosin comes in a round cake attached to a protective suedette cloth in a velvety material pouch. A fine choice for violin, viola and cello.
