These rolls make it easy to teach any music lesson. The printed staff lines are large enough to be seen from the back of class, and with the patented dry erase coating it can be used over and over again without shadowing. It has a full adhesive back that won’t leave residue behind and sticks to most clean, smooth, hard, non-porous surfaces. Each film-wrapped roll has a hang tab attached making them peggable, or the rolls can be displayed on a shelf. Recyclable.
