Missing Handcuffs

A slight mystery has come about here. I am attempting to locate a pair of Galls Standard Handcuffs that I have not seen in a while. The cuffs are fairly cheap, but I was hoping to use them to make a more complex restraint (utilizing the cuffs, a connector chain and a pair of boot size leg cuffs). I recall the cuffs being placed in my under-bed toy box, but I have all but turned the box inside out looking for the cuffs, as well as other locations for storing of restraints. Where could they possibly be? A present theory is that I may have loaned/given them to a friend, but at the present time I don’t remember doing so. If I have loaned you a pair of cuffs resembling those below, please let me know, so that I may properly update my records. If you have my cuffs, you may keep them, I won’t ask for them back, but I would like to be able to update my records to properly indicate their status (given to____, lost, etc).
