A new envelope system for letters consisting of an envelope made so that, cutting its development on a sheet of paper, two small lateral fins that fold inward are gummed with the lower body of said development. The upper part of the envelope has three lines of holes; between the first two, a tape is glued, whose right end protrudes a little (one centimeter) and the upper part is folded by the second line of drills, the envelope is made, instead of being an ordinary angle, it is bordered by a curved line of shorter length, which makes the operation of pasting the envelope less cumbersome.
