Astound and amaze with the Chicago Model 1550MG handcuffs. These cuffs are heavy, fixed, metal cuffs in an Irish-8, but there is a trick. These handcuffs have no spring. Gravity alone locks them when turned the right way up, showing what appears to be a sturdy and firm restraint. With a simple flourish and a flip, the locking pin falls away and handcuffs open. Also includes two screw in keys.
