These are perfect for my pendants that have very small loops or openings.  I have several other leather cords with clasps, but the clasp hardware is so big that I can't get them through the loop on the pendants.  These are perfect for the smallest loop.  The drawback is that it's a little more difficult to open and close the clasp, but that's preferable to not being able to wear the pendants at all.  The 14" is just the right length for small pendants that I want to hang just above the neck opening of my shirt.
