I have bought these a couple of times and they are very good. The self-seal is good and the envelopes are high quality.

I gave these Tyvek envelopes a five-star because the product was high quality, the cost was one-third of that at the office supply store, and delivery was within 48 hours. I had purchased a pack of five Tyvek envelopes for $5.34 at an office supply store to see if I liked that product for mailing my investment book to purchasers. It worked great, but the $1.07 per envelope was a bit pricey. Amazon did the job for about 35 cents per envelope, and delivered for free.

Constructed with strong material to prevent tearing. I wished I had bought the envelopes with expandable sides.

We bought these to replace our use of USPS's priority envelopes. By packing them ourselves, we save anywhere from $3-10 per mailing. The envelope isn't as nice as the USPS ones, but I didn't care about that. All I care about is that they protect what I am shipping and they hold up. They are strong envelopes and I don't expect we will have any issues with them at all. They get the job done and we will continue buying them.

I recently began selling my old stuff online. I purchased these envelopes for mailing shirts to my buyers. They work perfectly for this!The envelopes seem kinda thin. Light does shine through, and you can almost see what's inside. However, there is just enough security not to be able to read the packing slips inside. The Tyvek is much stronger than you would think.The envelopes have a peel-off protector to expose the adhesive flap. Where you are supposed to stick the flap has a perforated section for easy opening. I do not trust this perforated strip to stay shut during shipping, so I always stick the flap further down on the envelope.I will buy these envelopes again when I run out.

Heavy duty quality envelopes that worked really well compared to other products online. They are worth a little bit extra for a quality product.

Bought these specifically to reinforce the inside of spines from old hardcover books to make junk journals. Much better than tyvek plastic tape rolls. It takes the color of ink perfectly also. This box will last me a long time.

I used them to mail material in presentation folders. These envelopes do not tear easily. Yet they can be opened easily when they need to be opened.
