I am also selling a postcard collection☺︎ ● After opening, I store them immediately in OPP bags. I will package them with cardboard protection on both sides + OPP. ● I will discount items that can be bundled by 100 yen. Conversely, individual sales are also possible, but the shipping cost will be higher. ● I may remove the listing without notice because I am also selling on other platforms. Thank you for your understanding.
