Ok so there's a good chance that everyone and their mom has these, but this is the first I've seen of them, and I think they're super cute. I want one! http://www.sliderbracelets.com/
I know of this really good company called Elite charms at www.elite-charms.com and they sell virtually every type of charm you need. I actually got my sorority on my charm bracelet, and so did allot of others. They are really cool, they just custom make them for you. I love Italian charm bracelets.
I forgot I started this thread 'til someone bumped it up! Since then, I've really added to mine! I have:
a Mickey Mouse October charm
an Easter basket
a CandyLand charm
a slipper orchid
Pi Beta Phi
Chi O Mom and AOII Mom
Easter Peeps
the flags of Japan, the Philippines, Guatemala, Vietnam, & Mexico
a Shih Tzu
candy corn
and a Nativity scene!
They ship same day and tell you where the charms are made. Most of what they sell is real italian stuff, and they tell you if it's not. They are also very good about returns on defectives. The owner is a Gamma Phi, so they carry all the soroity charms.
