This handy little item is a genuine set of handcuffs - these are NOT play cuffs or a cute piece of jewelry, it's the real McCoy! It comes with two keys, and can be "double locked." That is to say, they can be placed on someone's wrists, and then locked in place so that they do not become any tighter.
OK, where do I start? If you are already into BDSM, you will find these to be a great item, restrictive and rather intimidating in appearances. But, you MUST have absolute faith in your partner, as these things do not have quick-release button, and cannot be removed without help. This is for-real bondage.
If you are just starting out into BDSM, then I would NOT recommend these. Like I said, they require a lot of faith in your partner, and if they are locked on too tightly, your hands will be in danger. Plus, who can forget Stephen King's Gerald's Game?
So, I recommend this item to those heavily into BDSM and who want some really restrictive cuffs. I do not recommend it to those just flirting with BDSM.
