I have a few silver fobs I use on bags with gold hardware. Sometimes everything else on the fob matches so perfectly that I overlook the hardware color. If you are really hardcore, some people switch out the rings to change the hardware color.
Usually I pick a fob because I like it. Whether or not it matches a purse I own is secondary. Sometimes I'll find the perfect purse to match it much later so I'd hate to have passed up a fob I liked just because I didn't have a matching purse. I have some I've had for a long time - I've never found anything to match but I still like them.
This starfish turned out to be perfect for my edgepaint mini Preston. I think they were from the same collection.
Wow, adorable!
