Thank you for viewing! I was impressed when I saw it on a TV program, and then I started the challenge. I came up with this after various工夫 (ingenuity/creative efforts). It's all made of cardboard, and I've also applied a waterproof coating. I'm planning to use it in various ways and create a fun cardboard long wallet. Thank you. ☆The product is only the cardboard long wallet (the card, bills, and coin stand are all samples).
