Ideal for organizing documents. 【Body Size/Weight】 (Gauge) W289 x L72 x H14mm / 110g (Punch) W72 x L51 x H46mm / 176g 【Hole Diameter】 5.5 mm 【Hole Spacing】 9.5 mm 【Hole Depth】 3.6 mm 【Compatible Size】 B5 【Compatible Sheets】 5 sheets 【Number of Holes】 26 holes / B5 Color: Blue Why not just use a 2-hole punch??? By using the number of holes for loose-leaf, there are advantages that 2-hole punches don't have. ・Because there are many holes, the stress on each hole is reduced, making it durable and less likely to tear even after repeated flipping. ・Holes are punched close to the edge of the paper, so the holes don't overlap the content of the page (from the edge of the paper to the center of the hole, gauge punch: 6.35mm, 2-hole punch: approx. 12mm) ・You can bind materials together with your loose-leaf binder, so everything is in one book (carrying two books, a 2-hole file for binding materials + loose-leaf for taking notes, is a bit inconvenient, isn't it?)
