I bought this rosin for my daughter's new bow. I was told that the rosin that comes in your violin case is usually rubbish and that a good quality rosin makes quite a difference for your bow, strings, and violin sound. So I desided to try the Pirastro goldflex . It really is much better than all the other rosins we used. Just a little amount on the bow hair is enough so it will last for a long time and to give a little more money for better quality rosin that lasts for years I think that is a good investment for the instrument .
This rosin has low dust formation so it will not damage your violin,bow or strings.
Package is quite nice with plastic base and tissue, so it is also very easy to handle.
I am very happy with my purchase and recommend to all violin players!
