#10 Windowless Security Envelopes Create Completely Secure Mail
We understand how difficult it can be to find secure envelopes that completely secure and hide your envelope contents throughout the mailing process. We understand this frustration; thus our envelope design protects your contents within a permanent and long lasting flip and seal flap.
Unlike weak sealing envelopes that allow your contents to fail out and become exposed, our strong seal will guarantee the safety of your contents.
A windowless envelope is the safest type of design, offering zero chance that your secure information will be exposed through transparent windows during transit. Just write on or add labels to address the envelope.

- It's simple to flip up the bottom flap and press down the top flap to seal
