Beautiful washable plastic shirt. Rugged, waterproof, rigid, sober. Nice finish ... Tel closing with elastic for not lose any documents. 2 extra folds on the side allow, by simple pressure, form a perfect size setting based on the number of sheets you want to store. À4 format. His colori (which pulls more on the purple than dark blue) allows both professional use and for high school. Then of course there are cheaper on the market ... But not as good. Leitz, products that are made to last !!
