The best use for the nickel handcuffs is to restrain for sexual purposes. My fiance likes to restrain me so I cant push him away during oral, and so he can do what he wants with me. I don't believe that this is for beginners. Beginners should use the fuzzy cuffs.

My opinion is that they are designed well. The nickel cuffs are stable and dependable. They will not come undone or get too tight. Because it is nickel, the handcuffs last a long time. They may bite into the skin a little if you pull, but it actually adds to the intensity of the experience. They have a comfortable fit.

The handcuffs worked good to keep me from moving around too much, and I liked that I had control when I used them on my fiance. I felt that the product met my standards and worked very well for my purposes. There are many different ways to use handcuffs. Me and my fiance plan on finding as many uses as possible for them.

It is fairly easy to care for these, if they get dirty, just wipe them down. They are easy to store as well.

I feel that the packaging for this item was fairly discreet and easy to understand.
