Key Ring

	You will need the key ring or Carbineer Hook and some craft cord.
	Cut cord to about 5 inches. Tie overhand knot at each end. Thread into the ring or hook. Place the cord into the assembly tool and press in the back.
	And you are done. A dab of super glue to hold the back in would make the assembly stronger. Note: This is not super strong and may come apart with enough force. For sure do not give to small children as any of these buttons may present a chocking hazard.
