The Mark!Set!Go! Silver Fingerboard Tapes were developed by Pearl Jones so both teachers and students can have a convenient way to mark finger positions on their instrument. No longer search for scissors. These silver precut glossy strips easily lift off and no time is wasted trying to remove their backing. These silver colored tapes are 2 inches long by 3/16th of an inch wide and fit all sizes of violins and violas and there's enough for 6 instruments. Precut felt adhesive squares are included. The squares can be used to mark thumb position placements as well, if desired.
