Please stop your unreasonable behavior. Intentionally spreading rumors about our products. There is no problem at all with our chain.You have chosen an inappropriate size yourself and the way you wear the tennis chain is incorrect. You unreasonably demanded a full refund from us, but you refused to return our tennis chains. And what we have embedded is 100% moissanite with diamond pens. If any customer buys a tennis chain that is not made of moissanite in our store, we promise a 100% full refund.
