I would like to say thank you for the friendly service. However, apart from kindness, it is unknown whether the product is a used product or a fake product. Because first of all, the delivery took 2 weeks. I understand. it's covid-19 Second, the engraving of the letter V part is peeled off. I have a problem with burnish silver. Third, the size is wrong. I know the US10 size is appropriate because I have worn all the sizes in the official Korean store. However, the us10 size of the ring I wanted was not available in korea, so I ordered it here. I ordered the US10 size, but it came in an absurdly large size. Fourth, the original invoice was stated on the website as mandatory, but I did not receive it. So the size was different and the authenticity was questionable. I also requested an invoice for repairs in Korea. However, the commercial invoice received by mail was arbitrarily edited and the order details were hidden in black. I can't check the order history at all. Usually invoices are written on real paper, but I didn't even get the real paper, I got the edited document. I felt infinitely grateful for the kindness and was moved by the responsibility of the staff. However, the low quality of the product and after-sales service disappointed me.
