What Makes Security Seal Envelopes Safer Than a Regular Envelope? The patterned 'Security Tint' printed on the interior of our self-seal security envelopes creates a tint that obscures visibility through the envelope's exterior, making it impossible to read the contents of the documents within. Without a security print, someone could easily intercept the letter and read some of it without ever opening the envelope. Our #10 Self Sealing Security Envelopes are a premium choice with a number of key benefits: - Large, windowless design, perfect for hand addressing. - Security tinted pattern, perfect for protecting sensitive information. - Perfect for thicker and larger documents. - Ultra secure self seal strip for quick, strong mailing. - Long lasting 500 envelope supply in every box, perfect for everyday use. ## Features - PREMIUM QUALITY SELF SEALING ENVELOPES- Ever tried sending an important document only for the recipient to report it has been damaged or compromised in transit? Any business or individual that respects the privacy of their recipient should consider investing in security envelopes as opposed to regular ones. Our self sealing envelopes are designed with a premium security tint to protect sensitive information as well as a super strong SELF-SEAL strip. - SECURITY TINT #10 ENVELOPES- Looking for security tinted envelopes that deliver maximum protection for confidential documents? Specially designed with check and highly confidential document security in mind, our quick seal envelopes will protect your critical bank routing and account information with the use of a fool-proof inside security tint as well as a windowless design. - WINDOWLESS ENVELOPES FOR ADDED SECURITY- Our windowless security envelopes are built to house standard business and legal documents, or any other confidential or sensitive correspondence.
