Does anyone know where I can get a pewter Sisters pin?

A year or so ago, I bought 7 pewter pins with five women holding a gold ball with the word "Sisters" on it. Since then, the store, from which I purchased these pins for my sisters and me, has closed. I'd like to get a few more, since some of them need to be replaced (broken, not fixable, lost), since we wear them almost daily and especially when we get together. If you can tell me where I can buy them, I'd would be so grateful. Please don't refer me to the tri-metal (sterling silver, copper, and brass) ones. They are all over the internet, but not for what I'm looking. Thanks for you help.
