if we have 10 swappers you all send me 9 charms and then I send you back 9 different charms...one from each of us... for you to make a bracelet or whatever..send the charms with rings attached and return postage ..approx. $3.00..easy and fun! Charms you send me need not be all the same but they can be. International swappers ...of course your return postage will be more like $6.00 and I cannot insure unless you pay for insurance.
