Six Grover Style Tuners - 3+3 (3 left and 3 right) with super cool red dice heads! Included are washers, threaded hex bushings and screws. Metal heads are removeable. Precision 14:1 gear ratio makes for very accurate tuning and prevents backlash. Very good quality chrome plated metal. Pretty that Baby up. Will fit many Gibsons and more guitars (even some acoustics), any guitar that uses 3+3 grover tuners with a center screwhole - please consult the measurement chart below for more specific sizing.
