Mail your communications in style with a wide range of rectangular envelopes. Whether you're running a home or a business, you'll need mailing supplies. Mail bills, invoices, checks, invitations, documents, and greeting cards using envelopes in a wide variety of sizes, shapes, and colors.

Traditional Business Envelopes
Mail client invoices, checks, and documents with traditional business envelopes. Choose single or double windows and use computer software to print customized checks and invoices that fit those windows. Avoid hand addressing envelopes and save hours of time, or include a blank window envelope with your invoices and make it easier for clients to return payment. Business envelopes come with self-sealing closures or gummed closures. Say goodbye to basic and choose a color that coordinates with your brand. Safety features like a tinted liner make sure your private documents stay that way until they reach the intended recipient.

Formal Stationery
Save money on wedding plans by making your own invitations, and use rectangular envelopes to mail them. Choose a paper color that coordinates with the invitation itself, and opt for traditional invitation sizes, such as 4 3/4 x 11 or 6 x 12. Add a touch of flair with foil-lined envelopes that match the metallic font on your invitations. Stationery envelopes aren't just for weddings: use them to mail company holiday cards, graduation invitations, or notifications of company award events.

Booklet and Document Size
Mail pamphlets, catalogs, closing documents, and other large materials with rectangular mailing envelopes. Pick from traditional brown paper construction or lined vellum that keeps the contents safe until they reach the desired recipient. Many mailing envelopes include a top closure, and some are self-sealing with detachable tops. Whatever your purpose and style, there's a rectangular mailing envelope that works for you.
