I have to punch me bought my Filofax A5 diary to. First, because I partly want to punch more sheets, and because he is supposed to be last longer and somewhat stable. In addition, the punch will cost from namendlichen organizer manufacturers already more than four times.
On the first attempt to use the punch, first came a big scare. Verdamt the thing has not the same size as my hole. Unfortunately, in the delivery no short description is included. At closer look, you can explore smaller strokes. Indicating the holes of different sizes DIN A. So, at the risk of destroying the thing just wiggle around even think about it and lo and behold, the little "Stanzerchen" can be moved well and bring in the right direction.
On the whole, I finds class and would recommend it to anyone.
