Martin Yale Master® MP3 3-Hole Punch

Item #: 04MYMP30

The Martin Yale Master® MP3 three-hole desktop puncher will punch through up to 20 sheets of paper* at a time, using an over-sized handle that spans the width of the machine so it is easy to punch through those stacks. It punches three holes with standard hole spacing for letter sized documents measuring 4 ¼" (center to center) between the holes. The holes are slightly over-sized, measuring 9/32" which makes for easier page turning and even allows for the possibility of using larger prong fasteners and other binding devices. The paper guide is adjustable to help you perfectly center your sheets. Storage of this office hole puncher is easy and compact when you lock down the handle. The non-skid feet help hole the hole punch in place securely while punching. Buy the Martin Yale Master® MP3 3-hole punch online with confidence knowing that it is made of heavy gauge steel and can be used by the whole office.
