In short, to open the lace end hardware: use a thin, sharp object like a box cutter blade, and slide it into the grove in the lace end. Twist and the lace end should pop open.
To close the hardware: make sure you seal the ends of the lace by heating them with a flame. Lay thee laces into the lace end hardware, close the “clamshell” and, if necessary, use a pliers to press the hardware together until you hear the 2 parts snap into place.
