Set of three clear top protectors made from a lighter, stronger and harder base material than the standard cling vinyl. Also features a new adhesive formulation that is non-reactive to most guitar finishes. Completely removable and repositionable. Can now be used on guitars with matte/satin finishes. Intended for classical/nylon string guitars. Two pieces fit on either side of the strings, between the soundhole and bridge, the third fits behind the bridge where string changes can scratch the top. Protects your guitar from heavy playing or fingernail tapping. Non-permanent. Note: use care when first applying this due to the many variations in guitar finishes.
