Nickel plated adaptor with stationary screw allows
for easy addition of concho (not included). Slide the long end in to
your pocket with the concho hanging on the outside.
When keys are needed, simply pull on the concho and
keys pull right out.
Before attaching concho, place a small amount of a strong glue
(Gorilla Glue, E6000, etc) in the post on the back of your concho.
Push the post down on the screw and twist the concho 
three to five rotations (different conchos have different length posts)
until concho image is upright compared to the key ring. 
Let dry overnight and you're ready to go.
