Now you never need to be without cuffs again.
 
Introducing the Wolfram Secret Cuffs.
 
This seeminly innocuous leather bracelet can be worn inconspicuously throughout mundane life. On the road, at the workplace, even to conservative family events. But flip it insid-out, and it becomes a pair of surprisingly durable handcuffs ready to restrain at a moment's norice. Open it all the way and it can also become a collar.
