Red Window Display Envelopes

The collection includes standard #10, A7 full-face, 6 x 9-inch full-face, 9 x 12-inch open-end, #10 full-face, and #10 invoice double-window options. JAM Paper red window envelopes are available in several sizes, from standard #10 envelopes to larger 9 x 12-inch options. This range supports invoices, business correspondence, invitations, promotional mail, reports, announcements, holiday communications, and branded inserts.

Paper weights include 24 lb and 32 lb, giving businesses options for standard correspondence and more substantial promotional or presentation-focused mail. Single-window styles handle everyday addresses, double-window layouts support invoice information, and full-face windows display more of cards, artwork, or printed inserts. Open-end 9 x 12-inch envelopes provide additional capacity for reports and larger business documents that should remain flat during mailing.

Most full-face, invoice, and larger open-end options include peel & seal closures for quick preparation during recurring business mail, seasonal campaigns, and event fulfillment. Red paper adds strong visual impact for holiday correspondence, customer communications, promotional pieces, billing, and branded mailings. The combination of multiple window styles, business and invitation sizes, and larger document mailers makes this collection useful across both routine office workflows and high-visibility campaigns.
