These cords are perfect for lacing your corset, they are definitely man-made - and i'm sure they are nylon based. The ends can be melted to make lacing up easier, but you would probably want to cut them of afterwards, so they don't look messy. They are made of a tubular braid, without a filler to bulk so while they are incredibly strong they still have around 5% stretch. This is not an elastic stretch, but the natural stretch any knitted product has. This is the same type of braid used by a well-respected corset company to lace their corsets, but i'm a traditionalist so its cheaper than the cotton! The width given is unstretched. Excellent cord, for corsets or your boots, and you'd struggle to snap this whatever you choose to do with it! Stretched out around 5mm wide.
