Professional Mailings & Everyday Filing

These #11 regular envelopes measure 4.5 x 10.375 inches and come in a box of 500. The 24-lb white sulphite stock carries SFI certification and 92% brightness with a vellum finish. Two side seams under construction and a remoistening seal support reliable machine inserting and secure closure.

Offices sending invoices.

The side-seam layout feeds cleanly through most inserters and laser printers. Buyers who need a window for address show-through or a larger catalogue-style envelope for unfolded documents should look at a different format.

This single specification determines whether the envelope feels substantial enough for formal correspondence and meets organisational sourcing policies for certified fibre.

Questions about this item

Will the #11 Regular Envelope 4.5 x 10.375 fit in my existing letter trays and filing cabinets?

The 4.5 by 10.375 inch dimensions match standard #11 commercial sizing, so they stack neatly in most letter trays, desktop sorters and vertical filing cabinets designed for regular business envelopes.

How can I confirm the envelopes feed cleanly through my laser printer?

The 24 lb white sulphite stock with 92% brightness and vellum finish is rated for laser and inkjet use; a single test sheet should show crisp toner adhesion without curling or jamming.

Does the box of 500 include any window envelopes or peel-and-seal strips, or must I buy those separately?

The box contains 500 plain white side-seam envelopes with remoistening seals only — no windows, no self-adhesive strips and no security tint; those styles are sold separately.
