This is the highest quality black satin cord you can find today! The 2mm thickness is ideal for use with necklaces and pendants, but it can also be used to tie sachets and charms, hang fragile treasures without damaging them, or even as a delicate way to lace up light garments. Sold by the yard, there is more than enough for a necklace of any length, with a fair amount left for use wherever you wish!
