Sturdy Tyvek® material as expected.
Serves our needs well. The seal strip works great. We affix our label and it’s off to the races. No complaints.

Thankful.
This is a product that doesn't pretend to be anything it isn't. These are terrific envelopes - easily comparable to ones that cost a lot more. I looked around and couldn't find anything cheaper unless I bought 500 at a time.I would highly recommend this product and company to future buyers.

Great price.
The envelope does not have a tamper proof seal. I just add more tape to the opening. Great price though.

Perfect for my needs
These are very cheap compared to the ones at the local stores.A tip for you, if you are shipping priority mail via USPS, don't use these because you can get free ones from your local post office, or online to use just for priority mail.These ones are good for First Class Postage.

Five Stars
These are perfect for my business mailings. They stay closed and are not see through.

The best product on the market
The best product on the market! Rugged, durable and dependable. Not cheap, but for me, well worth the price. I never have a worry about my envelope tearing, splitting or opening.
