For the customer looking for some nice-looking slim padlocked restraints, this is just the item. Easy to use in fine leather, these will keep their little lover on the clampdown for a (love you) long time. So slim and sassy, they won't even know they're attached until they start to squirm, yelp, cry and sigh. Well, unless you get permission first (which is, by the way, highly recommended). Particularly effective since they're sold by the pair. One is fun, but two are dreamy. No batteries necessary.
