You have to keep your keys organized, so why not let a superhero be your key chain. I suggest this Superman 3-Inch Bendable Figure Key Chain.
You are not only getting a key chain, but also a fun figure to play with. Plus, this Superman figure is bendable so that you can pose him anyway you want. This is 3 inches of DC Comics fun that you will always have with you. Well, unless you lose your keys anyway.
This fun key chain is only $5.99 from Entertainment Earth. Pre-order it now and it releases in August.
