Mead #10 Security Business Envelopes Letter Size 4-1/8" x 9-1/2" – Peel and Seal, Privacy Lined, No-Window, Press-It Seal-It Self-Adhesive for Home & Office Mailing, 45 Count (75026)

I’m using these Mead #10 security envelopes for regular letter mailing and they do exactly what I need them to do. The peel-and-seal strip is super convenient—no licking, no sponge, just fold and press. The adhesive feels strong enough that I’m not worried about them popping open in the mail. The security lining is nice for checks or anything slightly sensitive; you can’t really see through them unless you’re really trying. Standard #10 size fits a tri-folded letter-size sheet perfectly, so no weird trimming or wrestling the paper in. They’re not super “premium” feeling—paper weight is fine but not thick or fancy. If you’re trying to impress a high-end client, you might want something heavier. And the pack is 45 count, which is fine for home/normal use but might feel small if you’re mailing stuff constantly. Overall though: for everyday mail, bills, forms, etc., they’re a good value for the money and I’d buy them again.

The envelopes work well, and the adhesive for the closure is nice and strong. They are thin envelopes, but they are not see-through due to the security pattern on the inside--I very much appreciate that feature. The size listed is accurate, and the color is pure white with no bleeding from the inside security pattern. You get 45 (I think?) envelopes in a box, and I feel like that is a great value, considering the quality.

Hard to rate an envelope. The size is as described, they are durable for mailing, the security print hides the contents, and the no lick peel and stick closure is fantastic. I mail my credit card bill so I do not care at all about color or design. I care they work, are peel and stick, have security, and are inexpensive. I've bought these several times and a small box generally lasts me a couple of years for the amount I mail.

These Mead #10 envelopes are a solid, standard choice for everyday business and personal mailing. The #10 size (4 1/8" x 9 1/2") is perfect for standard letter-sized paper folded into thirds, making them a practical staple for any home or office. ​The paper quality is typical for 20 lb. stock, which is decent for routine correspondence, though some users might find it a bit thin for mailing highly sensitive documents (unless a security-tinted version is used). They usually feature a gummed closure that requires moistening to seal securely, or occasionally a "Press-it Seal-it" self-adhesive flap, depending on the specific pack purchased. ​They get the job done reliably for checks, invoices, and general letters. They are a cost-effective and dependable option when you need a basic, professional-looking envelope without any special features.
