Marsh's Music Staff Markerboard is imprinted with five sets of permanent staff lines, making it a great choice for your band or choir room. Fill in your music and easily wipe away the notes – but not the lines – at the end of the day. The porcelain markerboard resists glare and scratches and is backed by a 50-year warranty. The lockpin system ensures that your board will not swing while you write. Choose music lines on both sides or music lines on one side and a plain markerboard on the flip side.
