The Thumbcuffs are one of those small things that get easily overlooked.
Which is a shame, because they are a ton of fun.
Sure, they're never going to be mistaken for serious, heavy, inescapable bondage gear, but they are a suprisingly efficient way of temporarily immobilising a partner. Being small, they are totally nonthreatening, but they do grip the thumbs quite nicely, just below the knuckle. Or big toes, for that matter... Captives can be easily attached to street lamps, soft furnishing displays, other captives, chain link fences, and much much more.
This is Microbondage that fits in a pocket and doubles as a wristband, or even, we've heard, a cock ring. You can't entirely resist this thing, and you shouldn't really try!
