Want to make your own professional-looking reports, booklets, or presentations? This manual binding machine is a handy little desktop tool. It punches 6 holes at a time, with a hole diameter of 6mm and spacing of 9.5mm, which is standard for many plastic or wire binding coils. It can punch through about 5 sheets of standard paper in one go. It's designed for common paper sizes: A4 (30 holes), B5 (26 holes), and A5 (20 holes) – just use the built-in ruler to line up your paper perfectly every time. Made from strong alloy steel and ABS plastic, so it's sturdy and should last. It comes in a few colors like white, blue, or pink. You'll need to buy the binding coils separately, but this punch does the hard part. Great for small offices, teachers, students, or anyone who needs to bind documents at home without a big, expensive machine.
