Jade rosin produces a smooth yet firm grip. From symphony musicians to concert artists, Jade rosin has met with enthusiastic acclaim. JADE rosin is made by a venerable French manufacturer, steeped in formulating professional quality rosin for well over a century. JADE rosin is a new, refined formulation, with remarkable qualities of dust-free adhesion. Avoiding metallic residues, which do not contribute to adhesion and may indeed scratch fine varnishes, JADE rosin incorporates highly refined resins to produce a smooth yet firm grip. From symphony musicians to concert artists, JADE rosin has received enthusiastic acclaim. Each rosin is mounted on a protective velvet cloth wrap and comes with its own attractive lidded container with gold and slate graphics.
