SOLUTION: The enclosure comprises the printed matter 10 with information 12 enclosed in an envelope 20 made of a transparent film. The information 12 is printed in black on the printed matter 10, and a specific region among such a region that can be seen through the transparent film from the outside is made into a colored region 11 by a color other than black. In addition, on the envelope 20, a region opposite to the colored region 11 at least when the printed matter 10 is enclosed is made into a colored region 21 colored by a color complementary to that of the specific region.
