D'Addario shows how innovative they can be with the introduction of the new Kaplan Premium Rosin, which comes in an easy applicator that doubles as storage cases.

Available in light and dark, it is suitable for violin, viola and cello bows and the special Kaplan recipe produces less dust, keeping hands and instruments cleaner. The rosin comes attached to the inside of of the applicator case, which "locks" shuts for clean, easy storage in an instrument case or bag. Once the tabs are squeezed to open the case, the rosin is then applied right from the case, where it can be rotated for uniform wear and maximum use.
