Quality Park 6 in. x 9.5 in. #6 5/8 Commercial Flap Gummed Closure Postage Saving Envelope – White (500/Box)

Quality Park Security Envelopes have a reflex blue pattern that protects sensitive client information because it obscures the details of the contents, even when held up to light. Single window envelopes display the recipient’s address for simple bulk mailings. These postage saver flat mailers are made from a more durable 28 lbs. Paper than standard business envelopes so they will stand up to mailings. Each envelope is 6 in. x 9.5 in. for larger enclosures and has a moisture seal flap and side seams for a clean, professional look. The single window measures 1.38 in. x 4.5 in. and is positioned 0.88 in. from the left edge and 2.38 in. ES from the bottom. Stock up on boxes of 500 for bulk mailings.
