This pouch is the perfect size for your bankbook. Have you ever felt that common bankbook cases are too big when you just want to put in your bankbook, with all that extra space? This bankbook case solves that problem. The length and width are almost the same size as a bankbook. The flap is deep, so it won't open, and there are no zippers or buttons that get in the way of taking it in and out. I use it myself, and it smoothly holds 1 to 5 bankbooks. (Confirmed) When you're out and about, a bankbook on its own feels a bit bare, and having this pouch is reassuring for storage at home! It's also the perfect size for a paper wallet or a rosary case, so please use it for a wide variety of purposes.
