My main criticism is the extremely cheap perceived quality, the bungee cords to make from the outset a worn-out impression, the wallet itself is made of cheap plastic, which is so soft that the individual pages (yes, there are banner pages, not "subjects") from sticking together quickly. In addition, the "Fächermappe" purely physically hold up to 20 to 30 leaves, otherwise grind out the bungee cords from further and the leaves are out or buckling as it as I said yes, no pockets that could absorb completely the sides.
So who wants to store some individual sheets in his planner, ok. But who such a folder for a few single sheets attaches itself to the planner? Since you can put between the normal book pages sheets same. Class sets of worksheets, exams etc. Never fit in the wallet. I'll keep this only because return is hardly worth. I would definitely not buy the portfolio again.
