If you want to discourage people from opening your confidential correspondence, you should mail it in LockSafe®. A two-part seal on the flap breaks down when opened. When you seal it again, an 'opened' message shows under the flap.

Ideas and inspiration

• For confidential reports, proposals, and medical data, and all sensitive financial information
• Any attempt to open the mailer leaves clearly visible evidence
• Mailer is burst, tear and water resistant
• Adding your brand to a LockSafe® mailer tells the world that you are serious about privacy
