Good value for the money. Pre-glued flap saves time.

These are perfect for the situation I use them for. Quality as they go through the mail with no issues, appearance is awesome because I love the confidential portion of the envelopes. Thickness is better and very durable again for what I need it to do. Works well as I don't have to lick or use a water bottle with topper to close. These are security envelopes and they work great! Recommend them.

Great quality envelopes! The paper is thick and durable, and the adhesive seals really well without needing extra tape. Perfect for mailing letters, cards, or documents. I’ve used several already and they’ve held up great through the mailing process. Will definitely be ordering more!

Exactly as you’d expect. Standard self sealing envelopes that get the job done at a great price! Great for those who go through large amounts of envelopes.

I have purchased at least 5 boxes of these #10 envelopes with the self-sealing flap. It's a little hit or miss in the total love department. Sometimes it's got a super grippy to the very edge of each side of the flap, other times it's not as super grippy nor goes that far. As a safety precaution, I just add a little tape on each end of the flap because I'm shipping an item inside the envelope not just a letter. Other than that, I'm very pleased with the Amazon Basics brand and specifically with these #10 envelopes.

Good quality, decent thickness and security. I like the convenience of the peel and stick closure.

They do the job. And someday, the post office will be able to do their jobs with a whole system revamp. So about the envelopes: Not too flimsy, opaque enough for privacy, and the glue works OK. They'll get to the other end likely in good shape. I've run them though my laser printer and they print OK, but lately I've been manually addressing them and using a small return label, which adheres well to the paper. So, for the price, fine. I'd buy them again.
