Got a "Camaro SS" keychain from my older sister for Xmas so I won't bother with a 45th keychain, otherwise I would have. Mine looks like this:
And I'd prefer the size and shape of the keychain I have. It fits the profile of the key fob itself very well inside my pocket so it doesn't feel so bulky.
I already have my house and dorm key on there so I don't wanna take up too much space.
The 45th keychain looks cool though. However, if it was painted it would inevitably wear off over time. That's why they're all brushed aluminum or chrome.
