About This Item
Mail with the confidence of knowing that sensitive information is safe with these double-window security-tint gummed envelopes. Each envelope boasts a security-tint design that keeps third parties from reading the enclosed contents. These Staples double-window security-tint envelopes come in a 500-pack and have heavily gummed flaps that let you close them shut by applying moisture, so they don't accidentally seal until you are ready.
