Though they look like typical Toy handcuffs, they are not. These are a solid well made set of handcuffs. Produced in chrom plated brass, they have a heft to them. The key is a single bit key with an extension that gets around a simple ward around the keyhole peg. The double lock is a lever on the case which can be moved readily enough, reducing it's effectiveness. They only have two links as compared to the toy version's three - though they are solid and welded, as they should be. The bow has holes drilled along it's edge which engage in a "gear" that turns inside the lock box. The key simply moves the gear away from the bow to unlock them while the double-lock engages into the gear preventing it from turning.
