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

Best Investment I've made for shipping. These are fabulous! And appreciate the do not bend labels. Used for albums, magazine, hard pages, photo sheets, etc. Love the weight and sturdiness.

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.

I ship out a lot of 8"x10" photos and these are decent quality and thick enough to protect while keeping the weight of the overall package down below the 8 ounce threshold so that it won't increase the cost of postage to the next increment when sending up to eight to ten photos per order. One thing to remember is the measurements listed are for the outside of the package. So, if your photo or document measures 9"x12", it won't fit. It is best to get the next size up from the size of the document you are shipping. Since I ship 8"x10' photos, I would want an envelope that has dimensions listed larger than 8"x10" and the 9"x12" fits them perfectly. I also use them to ship my 7"x9" size photos. I didn't see much point in buying two different sizes since these can be purchased in bulk lots of 100 for about 37 cents per envelope. Another important note, even though these are "rigid mailer" they will still be slightly floppy just like the rigid envelopes from other sellers. What I do is cut piece of cardboard from recycled carboard that I would otherwise put in the recycle bin. I place the photo in an acid free plastic photo bag, then tape that to one piece of the cut cardboard and put at least one other piece of cut cardboard on top of that and tape it together. Then just slide that into the envelope. The addition of the two or more pieces of recycled cardboard in the rigid mailer makes it near impossible for it to be bent even if a postal carrier were intentionally trying to bend it in an attempt to squeeze it into a smaller mailbox. They won't be able to bend it, thereby protecting your photo or document from damage while in transit of being delivered. The "Do Not Bend" stickers are also a nice touch as well.

Works great, exactly like expected! Good quality and stiff enough for documents etc. Seals exactly like it's supposed to. It's not so stiff that it won't bend though - so if you need something absolutely too stiff to bend this won't be it, this is more flexible. Works great for what I need though, and comes with do not bend stickers, so I've never had an issue with it.

I use this item daily for placing orders. I appreciate its durability.

These have worked really well for shipping my comic books. They stay flat, feel sturdy enough for the job, and overall do what I need them to do - seal, adhere, and lightweight enough to keep shipping costs reasonable. For mailing comics and other items that you don’t want bent, they’ve been a solid option. My only frustration is that I’ve now had two straight deliveries where a noticeable portion of the pack showed up damaged. The mailers themselves are useful, but the consistency on delivery condition has been a little annoying. If that issue got cleaned up, I’d rate them even higher.

Mailers are fine. I will mostlikely still add chipboard inner support for extra protection of photos. Shipping and delivery substandard f. Stated next day delivery, was to be delivered on Tuesday, did not arrive until Wednesday and delivery instructions not folliwed.

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.

Solid structure and a good, strong adhesive seal. These are much better quality than others I've purchased in the past. I also appreciate that they come with do not bend stickers.

We use these all the time. Good sturdy packaging it’s amazing

Perfect

Love these envelopes.!!! They are quite rigid, don't bend easily. Have made it all around North America with fragile items inside and not one issue. I only wish they had a larger value package option.

My wife usesthese mailers to ship party banners, stickers, and vinyl decals, and overall they’ve been great. They’re sturdy, keep everything flat, and the self-seal and “Do Not Bend” stickers are super convenient. Orders usually arrive in perfect shape. The only downside is that in the last batch, 4 of the envelopes came damaged, which was a bit disappointing. Still, she’ll likely order again because they work so well for what she needs them.
