Leathermood Bespoke Rosin

This is rosin for violin. I purchased it on the recommendation of my teacher. It improved the sound quality and made the articulation clearer. The playing feel also changed, making it easier to play double stops. I now understand why it was recommended as magic rosin. I used it about once or twice a week for six months, but I've decided to give up on the violin, so I'm selling it.
