Thank you for viewing this page. [About the product] This item has been stored at home for many years. There are some rust and scratches due to aging and poor storage conditions. Therefore, it is listed as a "remake material" rather than an "accessory." The size is 20mm inner diameter, which is size 22. [About shipping] We are very sorry, but we will only use Yu-packet Post Mini. * We are selling at the lowest price, so we cannot negotiate a price reduction. * Bulk purchase welcome #Ring #Remake material #Metalworking
