very versatile. Easy to use for tying up, as tight or as loose as you want. Or use it as a blindfold. I like them, because they still have an elegant look to them, instead of the pink fluffy handcuffs, for example. Bought these together with the Fetish Fantasy Deluxe Love Mask, and they looked super sexy on my wife. they are light and small, so you can hide them in your pillow case for example, and surprise her. hard to do that with handcuffs etc.
