Our 5/16" diameter Black and White nylon rope is custom manufactured to our specifications, and in our opinion is one of the best bondage ropes currently available. It holds knots really well, and - this may sound like a bad thing, but isn't - it's highly kink resistant. So unlike a lot of other "bondage" rope, it won't tie itself in knots when nobody's looking! Being silky soft and thick makes it nice and comfortable, and it's long enough for lots of bondage adventures.
