Don't you hate it when your keychain is weighed down with unnecessary keys? I call it janitor keychain syndrome, and I used to suffer from it until I found this Tokidoki Heart and Crossbone Keychain ($25). Peel your eyes away from the sweet yet bad girl design and focus on the latch mechanism. The easily accessible link function allows you to switch out keys with ease. This way, I don't have to lug around 10 keys just for a stroll in the park. Pretty cool, huh?
