Folder with elastic band and 3 flaps made of Colorspan cardboard 355 g/m² - A4. These folders are made of Colorspan cardboard, a cardboard of unique quality, homogeneous and coloured, without varnish and without the addition of plastic material. It is more durable than any other cardboard in everyday use. 355 g/m² corresponds to a thickness of between 457 µ and 500 µ. Without back label, but with pre-print on the lid. This makes labelling the contents very easy. FSC-certified. The elasticated binder is 100% made in France, from the cardboard to the finished product.
