The Perfect Accompaniment Created by Larsen Strings, these rosins are designed to create a refined and delicate friction. The unique rosin recipes ideally complement the Larsen string range. For Violin, Viola and Cello: blends of choice raw materials have been specifically developed to match the requirements of the individual instrument to optimise adhesion, whilst minimising unnecessary noise, creating a seamless blend between bow and strings. Larsen Strings Rosin is available in two recipe variants for violin, viola and cello. Rich Amber Original and as Larsen Red. Please Note: Rosin is a natural material. Larsen rosin, in common with most naturally derived non-synthetic bowed instrument rosins, may cause an allergic reaction with some players.
