White Paperboard Rigid Mailers, 7 x 9 Inches. Pack 25 Chipboard Photo Envelopes Self Seal, 550 GSM. Stay Flat Box Mailers, 7 x 9. No Bend Self-Sealing Business Mailing Envelopes

I like the quality and the thickness. Picture attached of its weight.

Thank you very sturdy!

This photo mailer is great for protecting artwork.

I started to sell vintage D&D modules and comic books, and I needed a way to mail them so they were protected during shipping. I read the reviews of 450 GSM mailers but came away skeptical my items would be protected. I took a chance with the Amiff mailers -- they were about twice as expensive as the other stiff mailers, however the money was well spent. At 550 GSM, they're incredibly stiff and durable, and I feel confident my items will survive shipping with no (or very minimal) damage. I would purchase them again.

As a concert artist we've sent mailers all over North America. However, I'm now semi-retired but still mailing new CD albums. As can be seen in the pix, these are very sturdy and have never yet failed in the months we have purchased. However, when we ordered from Quill years ago, they had a mailer with room for addresses as well as the correct postage. These units are totally blank. For limited commercial use ok. For personal use very good except I still prefer the old Quill brand with lines to help with horizontal insertion of addresses (unless you use an app on your computer. Next time, I think I shall try to find a brand easier to hand-print. (Important to note we never have received any complaints of these mailers failing ). Lastly, if you use a flexible CD protector either paper or poly, that will easily fit in the mailer. This mailer will NOT accept hard plastic CD commercial packaging. For us, no problem. Thanks for reading. God Bless.

Did what it said they would do

These are very sturdy but can be costly when mailing. At USPS these went out as a package with a letter and poster inside at $5.40 each for 38 packages and for 7 packages various prices because they had more items. However, I still like the envelopes because they did not bend the posters which was a gift to everyone who donated to our fundraising.

Worked well and were the right size for my daughter’s artwork. Mailed great grandparents some of her crafts since we haven’t seen them due to covid, ans they arrived in great shape. They are very sturdy and the self stick made them really easy to pack up.

I used these to ship rewards for a crowd-funding campaign (art prints, postcards, and handkerchiefs), and they were excellent. These mailers were sturdy enough that I wasn’t at all worried about the contents being damaged, and the self-seal was good and strong. Best of all for me, they meet the size requirements for oversize letter-mail with Canada Post, and the envelopes themselves were pretty light-weight, so it was really inexpensive to ship out a ton of orders all around the world.

Works great for me

Thank you

With "Rigid" as the first word on the product listing, and a price of $30+ for a pack of 25, you might expect these mailers to actually be rigid. Sadly, they are not. They are far cheaper and flimsier than the standard-issue FedEx/UPS envelopes which you can get for free. They are very much bendable, and their corners and edges fray at the earliest opportunity.I would not trust these envelopes when mailing any kind of important document.

Not rigid at all. It is very thin and flimsy and would not protect its contents. Terrible quality.
