Avoid the hassle of drawing or taping staff lines with the Luxor Mobile Double Sided Music Whiteboard. Both sides feature five permanent rows of UV-resistant staff lines across the full six-foot-width of the surface, providing ten overall sets of staff lines to illustrate melodies. Simply loosen the side knobs and spring-loaded locking clip to flip the board or students can us both sides simultaneously. Staff line spacing allows for single or dual-clef notation. Both sides are also magnetic for displaying sheet music, announcements and more, and four casters make rolling the whiteboard around the room a breeze. Save more time and make more music with this mobile music dry erase board.
