Rainbow Braided Earphone Cord Kit

This one comes flat-packed as thread and buttons, and the braiding is yours to do.

Your earphones come out of your bag looking like everyone else's, which is how they end up borrowed and never returned. You wrap the thread along the cable and add the buttons as you go, so a plain white wire ends up looking like something you own rather than something that came in the box. No two ever turn out the same, and it needs no tools.
