Keep you’re strap from popping off unwantedly, and thus keep your instrument from crashing to the floor...also unwantedly.
This kit comes with two buttons to be attached by provided screws. The screws come in two sizes each, just in case you have a strap button hole that’s a little bigger than most they got you covered. Also includes two o rings to be used as a tight, non loosening washer. Install these elliptical buttons horizontally, then when putting on the strap rotate it 90 degrees to ensure it cannot pop over the button.
