One of my favorite ways to use charms (aside from as a necklace!) is as a bag tag. It's just a fun, personal way to express yourself. 

These keychains work both as a traditional keychain or as a bag tag...or maybe something I haven't thought of yet! It comes in 3 different finishes, and it's an inexpensive way to gift a charm to someone who may not wear jewelry. 

The last photo shows my current bag tag, which I added a snippet of vintage lace to.
