heavy，robust，good workmanship, do its job we'll, it can be used for long time. expensive but I found every cent from it,

In my job, I help hospital clients set up binders of required testing results, for review by regulatory/accrediting agencies. In my opinion, neatness counts in this effort, and there's nothing more frustrating and sloppy-looking that manuals full of test reports that have mispunched holes.This device has two features that ensure neat results. First, the paper guides at either side work together to ensure that the paper is always centered in the punch; and second, the locations of the punches are fixed, so they cannot go out of alignment.Although not the least expensive hole punch, the is far and away the best manual hole punch for creating professional and neat document binders.

This hole puncher works great! Easy to use, easily adjustable. I have done up to 50 pages at once and it works perfectly!
