Larsen Strings developed an exacting formula for rosins that produce refined and delicate friction that is ideally tailored to complement the Larsen string range. Larsen's in-house blend of choice raw materials have been specifically developed to match the requirements of violin, viola, and cello respectively, to optimize adhesion while minimizing unnecessary noise, creating a seamless blend between bow and strings.

Suited for intermediate to advanced players, Larsen rosin is available in two recipe variants; the original Larsen Amber and Larsen Red.

Larsen Rosin is made in Sweden.
