This is a very rare Milan Black Cat rosin from the aluminum can era. It is no longer manufactured, and the recipe is said to have changed, so many people are looking for it, just like the phantom rosin "Can Bell." The lid of the can has a slight dent, but the rosin itself is hardly used. The included cloth was damaged, so it has been removed. I will put some suitable cloth in the can to prevent the rosin from moving around. Enjoy a different sound with your usual violin and bow.
