This is a 6-hole punch specifically designed for system binders, capable of punching A5, Bible, and Pocket sizes. The design is excellent, and the original price was 3,200 yen (excluding tax). It has a sturdy and beautiful design, giving the impression that it will never break. The instructions on the last page are taken from the internet and are not included, but I thought they would be helpful, so please take a look for reference. This is a hard-to-find item, so please consider it. Thank you for looking.
