Where to buy connector rings for smaller fingers?

So I'm in love with those connector rings like this (a href="http://www.urbanoutfitters.com/urban/catalog/productdetail.jsp?itemdescription=true&itemCount=80&startValue=1&selectedProductColor=&sortby=&id=17756057&parentid=TRENDS_JULY2010WACC&sortProperties=+subCategoryPosition,&navCount=35&navAction=jump&color=&pushId=TRENDS_JULY2010WACC&popId=WOMENS&prepushId=&selectedProductSize=)" rel="nofollow"http://www.urbanoutfitters.com/urban/cat…/a except I have really bony fingers so everywhere I go, none of them fit me! Does anyone know where to buy them in Canada for a size 5? Thanks :)
