Kolstein's exacting research and development has brought us their Ultra Formulation Supreme rosin. Well-known for its low powdering and smooth, easy bowing. This rosin provides excellent grip and equates to quick response and consistent sustain for both veteran and beginning bassists. A silicone wrap keeps the rosin protected from chipping or cracking, and can easily be rolled down to expose more material.

Larsen Violin Rosin is a medium grade rosin formulated specifically for violin. Larsen Violin Rosin's special formula is melted in a vacuum which is totally free of oxygen eliminating most of the allergens otherwise found in rosin for stringed instruments. All of the raw materials used to make this popular rosin are natural and distilled without the use of harsh chemicals that can subsequently attack bow hair. Larsen Violin Rosin is a natural product containing no harmful substances.

Pop's Bass Rosin is the number one best selling bass rosin. Many bass players use it year round because of the improved grip it delivers. Take care to clean the bass often as this rosin dries very messy on the instrument top. Use care when storing the bow, since the bow hair will retain this rosin for a long time. Storage of the bow case in heat can result in the bow hair becoming a large glob that requires 'washing'.
