Self-adhesive postal envelope, consisting of a folded sheet, topped by two of its end sides, by two parallel tabs, impregnated by their respective internal faces with a solution that repels the adherence to the paper, doing it instead on the face impregnated with the same material, which makes it possible that when the lower tongue is unfolded, the two impregnated faces face each other, a simple pressure sufficing to achieve perfect adhesion.
