500 #10 self-seal envelopes, excellent price, excellent quality
Box of 500 envelopes, self-sealing and security lined. Certainly good value for money. I chose the "used" lot from Amazon, which is their version of "dent and scratch." This just means the outside box was damaged, the envelopes inside were just fine. A good way to save money when you don't mind packaging issues. The thing I really like about these #10 envelopes is the seal. Once you remove the backing paper, the seal really holds. You can NOT easily reopen it without it being obvious. Adhesive strength is well designed. This is key when security is an issue. Also, on that note, the security lining makes it impossible to see what is inside the envelope. These are standard size #10 business envelopes, standard thickness, not too thin. It will protect the contents quite well. So I would purchase this product again. Very happy with my order.

Work perfectly and bo licking!
Good basic security envelopes. Adhesive seems to hold securely and you can't see the contents with the security printing inside of these. Great price when you buy in bulk.

Great Quality and Very Convenient
⭐️⭐️⭐️⭐️⭐️ These #10 self-seal envelopes are perfect for everyday office use. The self-seal adhesive is strong and makes mailing quick and easy. The security tint hides the contents well, and the envelopes feel sturdy with good-quality 24 LB paper. Printer-friendly and windowless, they work great for professional documents. Excellent value for a 500-pack—highly recommend!
