Review: Good brand and reliable quality - Good quality envelopes, no licking! They are standard letter size envelopes with the printing inside to obscure what's inside. The adhesive works well and saves you from having to wet a sponge, or lick some unknown chemicals:-). They are a good value as they are only a little more expensive than the generic ones, but are made form a little thicker paper to help conceal what's inside.
Review: Solid Everyday Envelopes for Cheap, No Complaints - 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.
