This is a notebook that can hold a bankbook and cash card side-by-side. It can store them together, and holds up to 8. It's useful for couples to manage where and when withdrawals are made, and seems good in case of emergencies. It's also great for preventing yourself from forgetting things. My household had a substitute, so I'm selling this. I received it at the end of the year, and it's practically unused. I haven't taken it outside. The regular price is about 2,600 yen. Shipping: Will be sent via Nekopos with air cushioning. Thank you for looking.
