Envelope with improved closure, and specifically those envelopes whose closure is constituted by a twine or cord that extends inside the envelope and that peeks out to open by tearing the envelope to pull the protruding end of said twine, characterized essentially because, instead of string or twine, a cellophane tape is applied to it, which is applied by glue along the closing flap, protruding to the outside for timely tearing of the envelope, and whose ribbon offers the width necessary to show appropriate drawings, colors and signs.
