摘要

Folder viewer, characterized by being formed by a profile that takes the form of an inverted "U" and whose length is approximately coincident with that of the folder on which it is attached, with the central branch of said profile acting as a spine on the edge of the folder, slightly curved in convexity to offer a better vision to the identification card contained inside.
