These cuffs are most likely only going to fit around your wrists unless you have tiny ankles. The leather is very sturdy and would suit anyone from amateur to more hardcore bondage play. I would not recommend trying to suspend with them, however, due to lack of internal padding.

These cuffs are pure and simple bondage wear. The external band of leather is strong and tough, while the internal band is a softer garment leather. These cuffs should last a lifetime if taken care of properly. They also have a lifetime guarantee if something does happen. ASLAN is a stand up company, and you should feel secure with this purchase. The cuffs also have a nice lock loop on the buckle, so no one is getting out of these!
While the leather is comfortable, it takes a few to fully break them in. A few minutes of bending and twisting should be all that is needed. Size wise they offer a wide range in wrist sizes, and again they should fit everyone.

These cuffs are great! I have used them a number of times and also personally been bound up in them. They are easy to get on and off, stay in place, and will not come undone unintentionally.
The leather is nice and soft yet firm enough to remain useful. I am very pleased with how well they fit and felt. They get better with age.

These cuffs are very easy to take care of. When not in use, I store them flat against each other.
To clean, use a damp cloth and dry well. To protect the metal, ASLAN recommends coating exposed metal with clear nail polish. This is a good idea, but I haven't had to do this or see a reason to.

The cuffs come buckled together in a clear disposable bag. They include care instructions but nothing fancy!

These cuffs work really well. In the past, I have had issue with cuffs cutting into my skin or just simply not being comfortable. However, these are very comfortable. They look nice and are impossible to slip out of. The cuffs do soften up with use and are very nice to wear.
