I am also selling a postcard collection. ● I have stored the cards in OPP bags immediately after opening them. They will be packaged with cardboard protection on both sides, plus an OPP bag. ● I offer a 100 yen discount for combined shipping on items that can be bundled. Conversely, individual sales are possible, but the shipping cost will be higher per item. ● I may remove the listing without notice, as I am also selling on other platforms. Thank you for your understanding.
