100 Pack 9X12 inch Self Seal Photo Document Mailers Stay Flat White Cardboard Envelopes White Photography Mailersfor CD, Photos, Document

Bought these for my business. They are very sturdy and seal well. Very good value for the cost.

Was initially skeptical that these were adequately strong mailers. When they first arrived, they seemed a little too flimsy. But after 3 restocks and 300 successful mailings later, these have changed my mind. The adhesive strip, while thin, is adequately strong to survive multiple days/weeks of travel, even from the mainland to Hawaii and overseas military bases. The feedback from the recipients has been consistently great. We do add an additional 1oz piece of cardboard inside for additional strength since the 1oz difference rarely changes our mailing rates. All in all great value for the price of 100 mailers + "Do not bend" stickers. zmybcpack has adequately convinced me to be a reliable brand.

Love these. Always order for my shipping needs. The adhesive closure is great, the size is perfect. They work well for lots of paper. Seal perfectly.

Great for my small business. They fit standard size magazines perfectly!

We've purchased these envelopes over 30 times (not kidding), and they've always met expectation. Our clients love that it's easy to open and documents arrive without wrinkles or torn apart. A couple of months ago we received one batch with a longer "peal & seal" which made it a lot easier for our team to close up the envelopes. Unfortunately we only got that version once before they went back to the normal "peal & seal" that's a little harder to remove to close the envelope. If the manufacturer ever reads this review, it would be awesome if you went with the version that has the longer "peal & seal" paper that can easily be removed. But either version gets the job done and this is just a small little detail that makes things .05% better.

This was a quick fix for this size envelope and the price was appealing. They are not as sturdy as the ones I usually use. I decided to try the brand that was less expensive. I will not use for photos without adding additional chip board. They just are not as thick as I had hoped they be. They are a nice envelope for the money. Just not the right thickness for me.

These cardboard envelopes are perfect for shipping packages! They are sturdy, well-made, and provide great protection for my items during transit. The size options are convenient, and they seal securely without worrying about damage. I’ve been using them for a few weeks now, and they’ve been reliable every time. Highly recommend for anyone looking for durable and reliable packaging solutions!

I really love these envelopes. They protect very well the transfers that I mail all the time. One envelope weighs approximately 2.4oz, the quality of the adhesive is very good and the white color. I bought hundreds of these envelopes for a couple of years now. I also love that they come with the stickers to do not bend. The only thing is that many Post Offices don’t consider them rigid enough to be mailed as a package (which gives you tracking). I have to insert a piece of cardboard every time otherwise you can have a label adjustment for priority. But I tested other brands and they are more flexible than these ones.
