Abstract: A resealable watertight mailing envelope has a Ziploc style strip for sealing the envelope closed. A flap portion is foldable over the Ziploc seal, secured in the closed position by a snap closure. The envelope also has an interior watertight lining joined with the Ziploc strip to seal the contents within from wetness or to prevent leakage of liquid items placed inside the envelope. In addition, a pair of adhesive strips can be attached to the inside of the flap portion for providing a water tight sealable closure of the envelope and also for alerting the individual that the envelope has been tampered with should the individual determine that the adhesive strips have been sundered from their engagement to the envelope's front panel.
