These wrist restraints are soft on the inside, and made for abuse on the outside. I believe they are an incredible product, good for all types of play until you become a truly serious bondage player and want to move to solid metal with locks. I love them. Oh wait, you don't want my opinion, you want details!

The fleece is attached to leather which is then stitched to the external leather. This is the only weak point in the design. I can't see how the fleece is truly attached - glue? Overall the restraints are made so well that I'm not worried, but over time this might be the area that they show wear. The fleece is thick enough to be quite comfortable.

There is a separate leather strap that feeds through the backing. This holds the metal attachments and the holes for fastening. All points are firmly attached with rivets that show every sign of being there until eternity. The O ring has an inside diameter of about 2 inches. Conclusion, quality and well made.

The O-ring is large and strong enough to tie rope to, and this is in fact what we did. The O-rings do not clip to each other. You would need a separate device to attach the two wrist restraints if that was a particular goal.

Tiny wrote a review of these restraints here. One of his concerns was that he had small wrists and found them too large. I honestly don't see how. These restraints come with seven different holes on the strap. I tightened it down to the smallest notch, and I found it was about the size of three fingers only.

If properly tightened, the wrist will have a hard time slipping through. At the risk of cutting off my circulation briefly, I put it on my own wrist far too tight. If you have a really tiny wrist you may lose a small amount of the padding as the overlap slips.

I do recommend caution when using bondage equipment. Check in with your partner frequently. Make sure that the wrist restraints are not too tight or that his/her arms are not elevated too high. Be aware of what might happen when they are released. In my case, the pressure holding one arm was released and I completely fell.

I wore these and was essentially restrained overhead. My wrists were comfortable, my arms were tired. This was more of a photography session than a hard bondage session, but I know that the restraints will both hold me firm and protect the wrist.
