So I had to get a key made.
And wanted to get a key chain to go with it.
[The Shotgun Shell key-chain looks to be more popular.]
I didn't check if you could put several of the small bullet key-chains inside the gun key-chain but figure somebody has.
So in addition to cute umbrellas, palm trees and hammers (?), there was, of course, a sniper rifle.
I guess if you are ever in a tight situation and left home without your real gun, you could always try threatening the bad guy with your key. "Back off, buddy."
Then while brandishing your key at buddy, you quickly unlock your front door and you're in!
Way better than waving an umbrella, or even a hammer, at him.
