Cons

•Paper isn’t premiuhick—adequate but not luxurious or extra sturdy.
•Pack size (45 envelopes) might feel limiting for heavy mailing users who might want larger quantities.
•A few users noted the flaps don’t always close completely on their own, requiring extra tape for security.

Bottom Line

If you need a solid, no-nonsense #10 security envelope with a reliable peel-and-seal closure, the Mead Press-it Seal-it envelopes are a dependable choice with great value for everyday business or personal use. They balance security, convenience, and affordability well, though if you require thicker paper or larger pack sizes, you might want to look elsewhere. For those who want standard, secure envelopes that get the job done without fuss, this is a great pick.
