The Binder Clip (Foldback Clip, invented by Louis E. Baltzley in 1910) is a reusable sheet fastener consisting of a tempered spring-steel triangular clamp and two collapsible nickel-plated wire loops. Available in standardized widths from Micro (1/2" / 13 mm, 30 sheets) to Extra Large (2" / 51 mm, 240+ sheets), it binds thick documents securely without punching holes or damaging paper fibers.
The No. 10 staple (standardized under Japanese JIS S 6036 and international formats as 10-1M) is the premier compact staple format measuring 9.3 mm crown width and 4.8 mm leg length. Engineered for compact, pocket, and ergonomic palm staplers, it is the dominant everyday staple in Japan and across East Asia.
