Super-Sensitive Clarity antiallergen

New for all bowed string instruments, this professional and advanced player rosin is clear and hypoallergenic. Made from a synthetic hydrocarbon resin compound that substantially improves the properties of rosin producing a clear string response. The hydrophobic material resists the absorption of moisture making it unaffected by humidity, keeping its tack and effectiveness over time. Non-corrosive to instrument varnish.
