Larica
Larica rosin is a high-quality brand of rosin for string instruments, particularly known for its "Gold" line which incorporates gold particles into larch resin to create a warm, clear, and vibrant tone. The different grades of Larica rosin have varying levels of hardness, from the driest (Grade I) to the stickiest (Grade IV), which are matched to different instruments like violins, violas, and cellos.
