The expensive original punch punch just individual pages, so I can not quite understand why this should be a criticism. I Allerding not corrugated sheets, so I do not know if that is a problem then. The fact that no plant bar to be present, I can not understand, with me is in any case a while, you just take off :-). It works very well in A5 sheets. For the smaller formats there is the centerline and yet different markings, where you can be guided. Since one has thought! I'm very satisfied! And have a lot of money saved given on the original punch.
