The Pressure Sealed Secure Mailer, sometimes called a Snap Pack, is a Secure Self Mailer that's perfect for sending private information like PIN numbers, medical bills, invoices, and anything else that requires discretion. The pressure sealed mailer is printed on 8.5" x 11" security paper that's bi-folded and sealed along the edges. The piece is not inserted into an envelope. Your recipient must fold, crease and tear the perforated edges to open the document and read the enclosed message. The Pressure Sealed Mailer is environmentally friendly because it doesn't require the use of an envelope, which also makes it slightly less expensive than an enveloped letter.
