I came across these nice, leather Fobs/Bag Charms on Amazon. I just ordered a few so I haven't seen them IRL yet, but at those bargain prices it's hard to go wrong. They're all listed as approx. between 3 to 4 inches -- not sure if that includes the hardware. Apparently they double as small zippered coin purses -- but they don't look humongous, lol.
The leather details look incredible to me...here's a screenshot of the Amazon page. Plus, they show a view of the front AND back for each one. (For privacy purposes I didn't send the actual link).
Free shipping too!
