Staples #9 Gummed White Window Envelopes - 3-7/8" x 8-7/8" - 500 Pack

Create a smoother mailing process with the Staples #9 Window Envelope. The window display shows your recipient's name and address on a form inside for better legibility and to save you the time and expense of having to add an addressee for every piece of mail you send. These #9 envelopes fit neatly into #10 envelopes- so they are ideal for use as a return envelope for memberships and other forms. They can also be used to send smaller sized invoices- statements or cheques. The gummed flap closure activates with moisture to create a tight seal while the 24-lb paper and side seams provide a durable finish.
