10 x 10 Square Envelopes

Calendars, oversized invitations, announcements, promotional materials, and specialty cards all benefit from the generous proportions of a 10 x 10 square envelope. The larger dimensions accommodate substantial square contents that may not fit conventional stationery envelopes. JAM Paper offers this size for business mailings, events, creative projects, and personal correspondence.

This collection takes two distinct approaches to enclosing larger square materials. White paper provides a clean exterior for formal correspondence and business pieces, while clear cello allows printed designs, photographs, and artwork to remain visible. Both styles support projects where the contents and overall presentation are equally important.

Additional space is especially useful for wedding suites, corporate invitations, holiday pieces, and marketing materials with larger dimensions. Clear cello styles feature Peel & Seal closures for convenient preparation, while paper envelopes offer a more traditional stationery style. The broad surface also provides plenty of space for addressing, labels, and other mailing details.
