The interchangeable cords have small screws at the ends which allow you to slide the strings comfortably into the rings of your Case 4U. The tips will then screw on at the very end! No one can see it and no one will know!

Sold in packs of two, you can change your cords to coordinate with your look as many times as you want!

Unscrew the end caps and gently slide the cord through the rings. Then slide the cord delicately into the adjuster; finally, screw everything into the end caps.
