Product Review; "I found this while browsing a local tag sale - I always love checking to see if there's any old American Products, after a quick cleaning and some new lubricant it was as good as new. I love the ability to take a magazine cut out, or an otherwise regular sheet of mail, finding the measurements to find my binder, and categorizing it professionally, every office deserves a workhorse like this Acco Hole Punch." -MadeInUSAReview

Only use Amazon links for info or if only option, some businesses don't have the means to distribute their own products, but using sites like Amazon should always be the last option
