Message Card Size: 5.5cm (height) x 9cm (width) The area for writing your message uses thin washi paper. Ginkgo and maple leaf chiyogami paper are pasted on both sides, making it a message card with an autumnal feel (⁠•⁠‿⁠•⁠) They are placed on the sides because if they were placed at the top and bottom, the area for writing the message would be reduced. It will be protected from water and sent in an envelope. I would like to trade with those who can provide some comments after purchase.
