I had been using Europa portfolio files bought in a local shop and found them really good. Thought I would try the Herlitz version to file assorted paper mementos. These are nice and bright, and sturdy enough. However, I hadn't noticed that the side flaps are glued on and shorter than those in the Europa version. The practical consequence I see to this is that the file won't hold smaller bits of paper securely, as may be visible in the photo I'm about to try to upload.
The board is a little less thick than the Europa brand, and there's a bit less of it in all. Also, the elastics are lighter. The Europa will probably handle a heavier and thicker load happily. However, for a reasonable quantity of A4 sheets, I anticipate the Herlitz files will do nicely and the Europa may be overkill. I am ordering some Europa files to keep my fiddly little bits of paper safely contained.
