These are more for advanced users but beginners can use too. It is wonderful for those who are looking for a way to stay restrained until your partner wants to let you out. If you fight against the restraints then this is also a wonderful product for you as you can freely move your wrists.

A full 360 swivel of each cuff lets you move your hands how you want to while keeping you securely held. Being metal it can rub and be potentially painful if you are not used to it. Made to last with a sturdy professional grade metal, it gives a nice cool feeling on your wrists. When used properly it should not cause much pain. Usable by everyone from a 5 1/2" to a 9" wrist. The double lock feature keeps you from accidentally over tightening once they are on.

These are best when used with your partner as it is extremely difficult for even the smallest of hands to get them off once they are on.

Being someone who like to fight against restraints I put them through a good bit more pulling on and twisting. Each cuff has a full 360 swivel where it connects to the links thus allowing you to be able to twist your hands around and get to what ever position is comfortable for you.

The double locking feature is extremely handy when fighting against the cuffs. Most handcuffs as you fight can tighten and become uncomfortable but the double lock feature prevents them from tightening once you have them on properly. Having small wrists this feature becomes extra handy as if it tries to tighten it becomes free moving and chaffs more.

When properly adjusted they really don't chaff but if that is a problem for you you can always add a fur or leather sleeve to them making them more comfortable and they will still fit and function like they do without.

If you are going to keep the key on your key chain then you need to be careful if you get pulled over or stopped by the police and make sure you inform them that you have it. It is a felony in most states to not inform them that you have the key but as long as you tell them you wont get into trouble.

Being made out of metal the best way to store them is to keep them in a dry place. If you want to clean them you can by spraying them with a light alcohol solution as they really don't need to be sterilized. Should they get some dirt in them, use a drop or two of oil and they will work good as new.
