TCH 822 Twinlock Chain Link Handcuffs from UK (has keyholes on both sides) [NIJ]
These are the twin keyhole version of TCH's chain link handcuffs. These are the "Superior" size, the same larger size that all their rigid handcuffs come in.
They are very nice and have all the same usual TCH quality and features, only that they have keyholes on both sides.
I like them.
