Review: No.10 Self-Seal Security Envelopes – 500 Pack - These envelopes are strong, reliable, and very convenient. The self-seal closure works perfectly—no need to lick or use extra glue—and the security print keeps contents private. The quality of the paper is durable and professional, making them ideal for both business and personal use. With 500 envelopes in the box, it’s a great value for the price. I highly recommend them if you need a large supply of dependable envelopes.
Review: Best "good enough" balance between price and quality - Are there lower cost envelopes? Yes Are there higher quality envelopes? Yes, these are obviously not premium envelopes Then why are these my envelopes of choice? Because these meet my standards of "good enough" at the lowest price possible. My use case is selling and mailing trading cards, by the way. These have all the features that I value at a cost that is currently less than $0.04 per envelope ($18.99 for 500). For my use case, self-sealing so that I don't have to lick, some type of security tint, and high enough quality paper so that I don't have to worry about damage are the most important features. Yes, there are things that can absolutely be better. So if you are looking for the absolute best envelopes, these are not for you. But my point is that these are good enough for most general use cases. I have yet to find something lower in cost that meets my standards, and anything higher quality than these is not necessary for most cases. Some examples of things that can be better: The security tint looks rather cheap but still gets the job done. The adhesive is not the strongest and the strip is not quite long enough to cover the entire flap, so there's always a small chance that the flap can get caught somewhere in the sorting machines and take the envelope apart. If I am sending something more valuable than usual, I'll sometimes tape down the edges of the flaps for peace of mind. With that being said, I haven't had a problem without taping down the edges.
