Accordion Note 100 Days Challenge to support 100 days challenge

Many people in Japan and overseas take on the "100 days challenge", and this notebook was developed to support such people. One page per day, 100 pages, is compiled into one book. The company's accordion technology, used in its "stamp book that does not bleed through to the back side," is applied to the notebook. It is a special accordion notebook that folds up to the size of a paperback book, and unfolds to a 10m panorama. When you reach the end of the 100 days, you can unfold it to a super wide 10m panorama and reminisce about the process of the challenge.

The accordion notebook can be used for any purpose, including studying (reading, drills), art (drawing, lyrics), music (live music, playing musical instruments), appreciation (movies, anime, astronomy), health (muscle training, dieting), travel (railroads, stamp rallies), sports (dance, running), nature (mountain climbing, fishing), and DIY (cooking, plastic models, handmade). Once you've completed your goal, you can display it on a wall or in a hallway as a panorama, share it with your family and friends, or line it up on a bookshelf as your self-history, bringing a sense of accomplishment that will put a smile on your face. The front is printed in pink and the back in blue, so it can also be used as an exchange diary for lovers or spouses.
