A new rosin from Thomastik-Infeld! This rosin supports focus, attack, and brilliance, helping to improve the strings' resonance and making clear articulation easier. Rosin comes in a sleek metallic case with a magnetic closure. Only with the violin version, a booster is included to enhance the grip and response of the bow as well as provide warmth to the sound. While a complex blend of ingredients from five continents complements Thomastik-Infeld strings, this rosin will expand the tonal variety on all instruments! Available for Violin, Viola, and Cello - Bass rosin coming soon!
