    Somewhere between small and large lies this ideally sized set of 6"x9" envelopes. Use them for everything from marketing magazines and legal letters to invitation flyers and office correspondence.

    Heavy Duty Composition

    Quality Kraft paper ensures each piece won't rip, puncture or fade with repeated use. Their ample blank space and light brown color accommodate both written and printed designs, so feel free to get fancy!

    Extra Strong Adhesive

    Convenient clasp fasteners easily lock contents inside for swift sending. You'll also enjoy additional backup bonding thanks to the gummed flap's superior stick quality.

    Open End Orientation

    Unlike booklet style envelopes, these prove remarkably versatile for everything that's pint-sized to oversized. Stuff folded documents and heavy catalogs with utmost ease and security.

    One Stamp Savings

    Maybe you don't need 500, or even 100. Our bulk supply meets your precise needs with 30 envelopes, so there's never waste or worry. You'll also save money on postage if it's under an ounce.
