It punches up to 10-12 sheets of 80g (≤20lb) paper, 2 sheets of 230g (≤85lb) cover/textured paper, or 1 sheet of 5-12mil PVC cover. With a maximum binding capacity of 450 sheets using 2" comb binding spines (not included), it's perfect for high-volume projects, delivering quick and professional results effortlessly. 【Precise Punch Alignment】Equipped with a positioning knob and adjustable edge guide, our book binder ensures accurate alignment for Letter, A4, and A5 sizes. Easily customize the paper margin (3mm, 4mm, 5mm) for professional-looking documents every time. 【Fully Assembled & User-Friendly】Unlike most binders with a single handle that require assembly, ours comes fully assembled for immediate use, avoid installation hassles. Our comb punch binder stands out with its advanced cutting blade and ergonomic Dual-Arm handle, allowing effortless paper cutting with minimal force. The durable cast iron base and powder-coated surface provide stability during punching, while the wear-resistant ABS plastic shell ensures long-lasting durability without cracking. 【Easy to Operate】Our binding machine is incredibly easy to use with just 2 steps! It features an all-in-one punching and binding system in one machine. Simply align the pages, press down the punching lever, and insert the comb. Be sure to press the punching handle all the way to the bottom without pausing, as stopping midway may cause paper jams.
