The Grover Star artist strap buttons offer guitarists a stylish way to securely attach their strap. Designed for serious musicians, the two-piece screw-on buttons easily replace your existing strap buttons without modifying or damaging your instrument. You'll love how the oversized die-cast buttons and custom-fitted O-rings safely lock your strap in place as you perform, letting you focus on your playing rather than constantly readjusting your instrument.
