4 1/8 x 9 1/2 Envelopes

Standard commercial mailers fall short when you need to send elongated contents without awkward folding. Sized at 5 1/4 by 10 inches, this extended envelope profile from JAM Paper provides ample clearance for tall promotional brochures and folded legal paperwork. The roomy interior allows inserts to smoothly slide into place during manual fulfillment.

Open-end policy styles feature a top flap on the short dimension to keep multi-page documents aligned for filing. Booklet options open along the long side so you can easily insert thick event menus or corporate financial summaries without crumpling the corners.

Move away from generic office whites with rich shades like deep copper or natural brown kraft. Choose moisture-activated gummed flaps for postal delivery, or select self-adhesive peel-and-seal strips that speed up assembly for wedding programs and special event announcements with large guest lists.
