GTFO!

To carry on the GTFO-WRIST-STRAP® simply insert two lengths of shock-cord inside the channel of the ANHUA MINI. The cord will expand and retain the key. To use the ANHUA MINI simply extract one piece of the shock-cord and slide it onto the AHK3-rf about 1mm past the key flag. There is no requirement to remove the keys. Pull the shock-cord from the channel of the ANHUA MINI, so the channel is clear. Hold the excess shock-cord between your thumb and index finger with the AHK3-rf in-between. Insert the ANHUA MINI into the key-way tube until it reaches the bottom and then rotate clockwise. Very little effort is required to open the handcuffs.
