Handle up to 250 sheets with a single 28 mm comb—the WALLNER S-100 brings heavy-duty binding power to your desk without taking up space. This manual comb binding machine punches through 12 sheets of 80 gsm paper at once, giving you a 21-hole rectangular pattern that fits A4, A5, and Letter formats. The lever-operated design keeps every punch crisp and consistent, while the integrated waste tray catches confetti for a clean workspace.

Overview

The WALLNER S-100 is built for small offices and home offices that need professional-looking documents in-house. Its ABS plastic body houses a metal punching mechanism, so you get durability where it counts without the weight of a full-metal machine. A 2-position margin depth adjustment lets you fine-tune the punch distance from the paper edge, ensuring a secure bind on thin or thick booklets. The document alignment guide keeps pages square, and the non-disengageable punches deliver uniform holes every time.
