This is a smart, perfectly-sized pouch for your bankbook. Have you ever felt that typical 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 to fumble with when taking it in and out. I use one myself, and it smoothly holds 1 to 5 bankbooks. (Confirmed) When you're out and about, a bare bankbook feels a bit plain, and having this pouch is reassuring for home storage too! It's also the perfect size for a paper wallet or a prayer bead case, so please use it for a wide variety of purposes.
