The Japanese Palm Stapler Benchmark
Pioneered by Japanese stationery maker Max Co., Ltd. in 1952, the No. 10 staple (9.3 × 4.8 mm) revolutionized office efficiency by reducing staple footprint on documents by 27%. Paired with modern flat-clinch mechanisms, No. 10 staples fold completely flat, eliminating the bulky corner humps that cause filed documents to lean inside folders.
