Kolstein’s Formulation Supreme Bass Rosin is composed of the finest ingredients and created through a high degree of product control with a minimum curing period for a predetermined time.

In addition to the strict developed formula, features such as hand pouring and packaging in a specially designed roll-down silicon unique containerization, all contribute to the superior quality of our rich, dark, textured rosin. The rosin comes in a protective silicon packaging that keeps the bass rosin fresh, preventing any kind of melting out of older packaging, and meets the needs of most bass players both professional and amateur.

Through extensive research and experimentation, Kolstein Bass Rosin has attained this unique and revolutionary Formulation Supreme. The result is bass rosin which has been fully acclaimed by our finest international soloist and ultra-professional orchestral and recording artists.
