BAZIC Self Seal White Envelope 4 1/8" x 9 1/2" #10, No Window Mailing Envelopes, Peel & Seal Mailer for Business Invoice Check (50/Pack), 1-Pack

They seem sturdy enough and the adhesive is good (and doesn't require licking).Perfectly adequate for the job.

These envelopes actually stay closed! A good value for the money...

These are average. Can find same quality less expensive in stores but I need them shipped to friend in nursing home who can only store small quantities.

These self sealing envelopes work well. Overall the envelopes are thin but decent quality. You don't need to tape the envelopes to secure them better. When mailing something, I felt I needed to put a piece of paper from a pad to hide the contents in the envelope. If you hold up the envelope to a light, you can see the contents. This was the main issue I see with this product.

Nice quantity, sturdy box

The envelope works, adhesion is good, thankfully no licking, tasting the glue and possibility of a paper cut on one's tongue. Seems to take both ballpoint pen ink as well as printer ink without spreading. Good envelope for the office/home use.

I use these daily for my business. I like the fact that they’re self sealing envelopes. CJ

I ordered the small envelopes, but they sent me the new big envelopes.What are bonus
