Message Card Size: 5.5cm (height) x 9cm (width) The area for writing your message uses thick paper with foil. (It's a little hard to see, but there's a thin silver foil.) The surface is slightly rough. Summer-themed chiyogami (decorative paper) has been applied to the right side, making it a summery message card (⁠•⁠‿⁠•⁠) It's placed on the right side because if it were placed at the top and bottom, the area for writing messages would be reduced. It will be protected from water damage and sent in an envelope. I would like to trade with those who can provide some comments after purchase.
