Which shops have keychains?

[chenoameg.livejournal.com]

After 24 years I have lost my first keychain. (It's been gone for the entire summer, I just need to accept I'm not going to find it.)

So, what shops in Davis Square have awesome keychains? Or maybe I mean key fob. The thing to go on the metal ring to make it mine. I'd like it to be durable enough to last in my pocket for another few decades.

(I realize I could go into all of the cool shops and look, but I have limited child free time to do window shopping in. Maybe there's the perfect keychain that you've been looking at!)
