This is a Kokuyo Harinacs Stapleless Stapler, its ingenious design needs no staples, no consumables. The shape of the binding hole is designed as an arrow blade which makes sure that the binding papers won't come off easily. Its compact palm size is ergonomically designed for one handed use and the power assist mechanism is designed to fasten papers with minimal force. There is a binding confirmation window on the top of the stapler. You can check the position of the binding hole and take out the the scraps and dust of the papers through the window.

Thread a lanyard through the small hole at the end of the handle to carry the stapler with you or hang it on the wall. Depending on the type of paper, the number of sheets to be bound may be reduced or may not be bound. You'd better try with unnecessary paper before using.
