Pratt MJ-2 Self-Seal Stay Flat Mailer, White, 7" x 9" (Pack of 100) (3 PACKS OF 100)

I've been ordering Pratt Stay Flat Mailers for over a year now, and I'm pleased with the product every time. I love that they have a variety of sizes to choose from, to suit each of my product needs.I was worried about the thickness of the mailers when I originally ordered them, beside the thickness (by inches) being available. They are 26pt weight for anyone looking for that method of measure. And no, they are not as thin as Priority Mail Flat Rate envelopes. They are thick, and hard to bend—ideal for prints, and other items you'd like to not arrive wrinkled. Keep in mind the rigidity also means you lose a little bit of the space on the edges—so for a 7" x 9" mailer, you can likely fit something 6.25" x 8.25" or smaller.Another worry I had: that the self-seal adhesive wouldn't be strong. I was wrong! I don't have to dab any glue on the edges for the seal to stick. I don't have to worry about them drying over time. I've had some sizes kept over months, and never had any issues with the seal.Overall, I'm very pleased with these mailers—great price, good stuff—and will continue to order them.

Ordered used from Amazon warehouse deals. Received with the brand Pac Worldwide embossed on the back of the mailers.Individual mailer weighs 1.6 oz and measures 7" x 9" when the flap is closed. The flap is on the short side, as pictured. The seam is narrow but strongly adhered.The description does not state the point weight, but the Pac Worldwide website lists a 26 point weight. This mailer is not the flimsy cereal box paperboard (or the USPS Priority Mail mailers). It is quite thick and inflexible, but will likely bend with intentional force if your postal carrier is careless.Rigid mailers will typically fit less than an equal sized mailer of another kind (such as a bubble mailer), so be aware of that when choosing a size.

Good quality. Will reorder. Nice and thick and the tab pulls do work well.Update: Reordered and product was not what I received the first time around. Was disappointed. These were flimsy, and had slits across the top. And the adhesive is now here near as strong. Contacted seller to inquire if product had changed and they stated no but I clearly recieved a different mailer. Not sure that I will be ordering again as these don't look as professional. Pictures for reference are of the size down as I was out of the larger mailer but other then size they were the same.

There are "good" quality and "not so good" quality mailers. I sell software, and use these to ship my products. The cheaper ones (not these) have a flimsy tear open tab, which really doesn't work worth a darn. And the recipient has to resort to scissors to really get it open.THESE (Amazon's) have a nice sturdy reinforced tear tab, and the recipient has no trouble opening it like a zipper.I used to buy from places like Uline, but to get the prices I had to purchase in 1000 lots and the freight was very pricey.Here I can buy as few as 1 package of 100 for basically the same quality and price. But I usually buy 200 at a time. <GGG>

Third or fourth time I have ordered these. Very sturdy and great for packaging up sticker sets. The issue I have is that the material they use to make these seems to change every time I order them. Also the last batch the construction is different as well. I still think they are a good product, but would prefer if they didn't change something that was close to perfect.

These work great for selling cards on my Etsy page. I can fit up to 6 A4 size cards with sleeves and envelopes. Anymore and you need a larger package. I got this so I could flexibly mail one or multiple cards and not have to buy a ton of different mailers.

These rigid mailers are amazing. They are super sturdy. I normally have to add an extra cardboard to my mailers to make sure they are thick enough, but I don't need to do that with these mailers at all! they are pricier than the ones I normally get, but its worth the quality.

Very good Item. Made of a very nice rigid cardboard that can prevent someone from bending the item. Tried a cheaper brand and went back to this... Good item. Decent value.
