Zusammenfassung: | PROBLEM TO BE SOLVED: To provide an envelope set for personal information protection capable of preventing leakage of personal information such as an address without requiring labor and time for shredding, punching, blacking out or the like when discarded.SOLUTION: The envelope set for personal information protection includes: an envelope 2 having a window W in which halftone dots 4 are printed; and a paper sheet 1 stored in the envelope 2. In the paper sheet 1, halftone dots 4 are printed in a range corresponding to the window W of the envelope 2. The envelope set for personal information protection is configured so that superposition of the halftone dots 4 of the window W of the envelope 2 on the halftone dots 4 of the paper sheet 1 displays an address 5 for delivery, and the address 5 is made difficult to be read by removal of the paper sheet 1 from the envelope 2. |
