What is big, has a Nightwing symbol, and is a keychain?  Why, it's the Big Nightwing Symbol Keychain, of course! Featuring a big Nightwing symbol in keychain form, the metal Big Nightwing Symbol Keychain is all you will ever need to show your love of DC's sidekick-gone-lone-wolf on your keys. I know I still have keys to my old apartment on my key ring, you think Nightwing has Batmobile keys on his? I think it stands to logic that he very well could. Anyway, whether a Batmobile, a Nightbird, or an El Camino, the Big Nightwing Symbol Keychain is a great place to put your keys.
