Won't stay closed!
These are a good price, yet won't stay closed in the mail. After losing a couple of items when packages came open, and seeing mailers pop open on the way to the post office, I now seal each with packing tape before mailing.
We use these envelopes every day for shipping merchandise. We've never had a complaint about tears or poor packaging. The envelopes are "soft" enough to mold to what you are putting in them, but tough enough not to tear.
