Universal Envelopes

Don’t feel like hand-addressing or hand-labeling dozens or even hundreds of documents? Universal plain window envelopes have covered openings on the front that display your recipient’s address, or both your return and your recipient’s address, printed on the document inside. Great at boosting mailing efficiency at home or at work, these essential office supplies have gummed closures that keep your correspondence safe and secure.

Double-Window Business Envelopes
Perfect for sending monthly invoices, billing statements, and mass marketing materials, among other printed documents, Universal’s double-window business mailing supplies have spaces for viewing the return as well as the recipient addresses on the papers inside. A great way to get through regular mailings quickly and efficiently, these mailers are comprised of 24-pound paper and have a tint on the inside that delivers an additional degree of privacy.
