How to make documents visible to everyone. Sometimes, documents, catalogs, plans, or other materials need to be easily accessible and readable. You don't have time to search for them in drawers or on the desk. Simply place them in a wall-mounted display holder like the Durable Vario. This holder, which has 20 pockets for A4 sheets, can be attached to the wall. A warehouse or factory will have many places where this holder is useful. However, these places are not the cleanest, and the people in these areas may not have the cleanest hands. Every touch of a white sheet of paper will definitely leave a fingerprint. But these pockets will prevent that. All 20-40 sheets are fully protected from dirt, dust, and water splashes on all sides.
