These proved to be awful. The seams are glued together so far from the edges that the "envelop" barely holds anything. The flaps also tear easily.

Excellent small padded mailer
This was the perfect size for securely mailing small Valentine's Day treats to our church's college students. We did have a problem keeping the return address labels adhered to the uneven surface on the envelope.

They were too large.
I sent in to return them and you sent a letter of credit. You told me to keep them no need to return.

worst enveloper ever
I have been buying these envelopes for years and lately they are so bad. They are glued unevenly on the sides and bottom so there is no clearance to put something in there to the bottom. They are uneven wrinkled and unusable. Not a recommended purchase

Good mailer but small
It has good padding and protection but it's a very tight fit for video game/DVD sized cases. I would recommend getting a slightly larger size if that's what you're shipping.

Mailers too think to qualify for First Class
I purchased these mailers for sending (very) small flat items. Because they are the correct size and (I thought) thickness they would meet USPS First Class mail standards - and only require 73 cents postage for an item weighing less than 1 ounce. HOWEVER the envelopes are 1/64th" too wide and so EXCEED the 1/4" USPS thickness requirement. Instead of 73 cents they a...

These have changed!
Just ordered 7/2024 and these are no longer made the same. Quality has went way down. Instead of individual envelopes they are now being made in a roll and perforated and torn apart. The seal flap is also smaller. In picture the top envelope is from 7/2024 bottom envelope is from 11/2023 same item # so I returned them.
