Kokuyo Harinacs Handy Stapleless Stapler (10-Sheet) | Japanese Eco Stationery

The handheld version of Kokuyo's stapleless stapler — binds up to 10 sheets of paper without a single metal staple, by punching and locking a small tab of the paper itself.

Kokuyo (コクヨ) is one of Japan's oldest and largest stationery makers, founded in Osaka in 1905. The Harinacs (ハリナックス) line replaces metal staples with paper-interlock binding — no waste, no jams, no refills, no separating metal before recycling. The Handy model (SLN-MSH110) is slim and ergonomic, and steps up to a 10-sheet capacity from the original's 5.

A built-in viewing window lets you line the bind up exactly where you want it; corner and side alignment markers help with edges. Punched paper flaps collect in a clear chamber you empty when full.
