D'Addario Rosin Guard w/ Rosin - Dark

The School Orchestra Director's Dream Product

Drop your rosin from any height and it just bounces. No more crumbled rosin crushed into the floor. It also helps to minimize contact with the ferrule when rosining, so the edges chip less. I can't believe it's taken this long for this product to be invented. Buy three. (It comes with a block of rosin, but any standard block can be placed in the holder)
