Andrea Sanctus rosin is a unique combination of two separate formulas. The outer part has a harder and drier texture, while the center is softer and more dense. The combination of the two formulas offers the best of both worlds.
The softer, center area is an enhanced formula based on the popular Andrea Solo rosin. The harder, outer area protects the softer center, and also provides a balance of sound.
All Andrea rosin is hand poured and made in the USA.
