If you use a replacement lace cord, which doesn't have lace tips or where the lace tips are too big, you will need to seal (melt) the tips before threading them through the stopper.

TAKE CARE!: Use a lighter to slightly melt the material of the lace tip. The flame does not need to touch the lace directly, only to melt the fibres through indirect heat. Only do this in a safe environment and under supervision if needed.

While the lace tips are still semi-melted, press each tip together with your fingers while twisting gently to create a thin, rounded ending.
