This item was perfect for what I wanted.  My mom bought a jade donut piece for me from Singapore and I went to every craft store I could think of for a soft black cord to loop around the jade piece with no luck.  Fortunately, this seller had the item and even comes in any length you need!  Good quality, sturdy latch, and has for the last month has been worn daily - work, working out, shower, etc and no signs of wearing down.
