Important documents such as testimonials or certificates can not only be protected from creases, dust or water splashes in the opaque cover, but are also covered from prying eyes on a transport route. The display folder is open at the top and on the right-hand side so that documents up to A4 size can be easily inserted and removed again. Papers can be sorted by subject and stored safely in the sturdy polypropylene document folder. The outside of the protective case is kept in plain white, while the inside shines in a strong grey.
