I have tugged on it to see the strength of it, it's pretty sturdy, but I'm not going to pretend it is top of the line lol, it is a generic made in china SINGLE handcuff keychain.
LOL! In the description, I mentioned that it is keyless. There is a little lever on the side that lets it loose...Also keep in mind this is one single cuff, not a double one like in the photo. Thanks!
