Each security tinted envelope has a scrambled blue pattern printed on the interior that conceals the contents. The patented SimplySafe seal is constructed to show any signs of tampering. These business envelopes are still easy for the sender to close and the intended recipient to open. The Release & Seal strip peels right off so you can press to seal without any moisture. A pull strip makes opening the envelope straightforward and prevents you from tearing the documents inside. Double window envelopes show sender and receiver addresses; the top window is 13/16" x 3-1/2"; 5/8" from the left; 2-1/4" from the bottom; the bottom window is 1" x 4"; 5/8" from the left; 5/8" from the bottom. Stock up on number 8 5/8 mailing envelopes with security tint for billing paperwork, tax documents, accounting records and more. Overall envelope dimensions 3-5/8 x 8-5/8 inches. White. Box of 500.

I still print and mail my own checks. I like these envelops because they are self sealing. They show up fast when I am running low and they are half the price of what the local office supply charges.

These are exactly like the envelopes you buy in a office product store, for half price. I have Quickbooks Pro program and the checks I print fits perfect with info showing exactly where it should. Good quality. Will definitely buy againðŸ‘
