These Single-lock metal handcuffs come with two keys. They have a safety catch to keep them from going any tighter than you want them to. They are very basic, functional, inexpensive cuffs for light bondage or accessory purposes.

It's a handcuff review by Geoff on 6/22/2016
It's a handcuff. Not much more to say, although do be a little careful when using these. They will sometimes get stuck if you try to unlock them while the safety catch is engaged. If they do, they can be fixed by removing the key, working the catch back and forth a few times, and then disengaging the catch and trying again. Easy enough, but a little scary the first time you can't get them unlocked.
