Quality Park Reveal-N-Seal Business Envelope

White side seam envelopes feature a unique, aggressive adhesive that provides a strong, moisture-free seal with six times longer shelf life than normal self-seal envelopes. No messy water moisteners or glue sticks needed. Just lift the flap and press to securely seal with no removable strip to throw away. Security is enhanced by an inside printed pattern and micro perfs along the flap that can reveal evidence of tampering.
