These portfolios with inner fold of plastic are the hammer, because they look like new for a long time, not that look tattered after a week as in conventional Pappmappen. However, I would fold itself these portfolios differently, I would hope that they will not be pre-bends, because I would myself these portfolios, as I have done well in Pappmappen, fold so that the rounded corners of both sides are each other. Schade..deshalb only 4 stars. The colors are very gaudy, from the yellow and green of the folder I get a headache, I'm not going to use! The shipping is super fast, which is to be expected because you pay a hefty 5 EUR Shipping! Whereby the Preileistungsverhältnis not quite match .. Se who tattered ugly Pappmappen not like and plastic loose-leaf binders from Aldi can not stand, they are great!
