Quality Park 6 x 8 Photo Document Mailers, Redi-Strip Self Seal Closure, Rigid Stay Flat Mailer, White Recycled Fiberboard, 25 per Box (QUA64007)

These envelopes are great and perfect what I needed them for. I’m mailing out my wedding invitations which have some embellishments on them and wanted something a bit sturdier than a regular envelope to protect them from getting damaged in the mail. These are true to 6”x8” size and made out of a thick cardstock, there’s no inside padding. My invites are 5.5”x7.5” with a little bit of thickness to them (about the thickness of 10-15 photos) and they fit snuggly in these envelopes. I wouldn’t really recommend anything much bigger than this otherwise it may be a too tight a fit. The total weight was around 3.10 ounces in which my invite was probably half of that. I thought I would be able to use a couple 2-ounce stamps (at $.71 each) on these but good thing I double checked with the post office first. Postage for domestic first-class mail came out to be $3.50 each. The postal worker assisting me advised that the envelope was considered a “special mailer” since it didn’t bend so the cost was a bit more than regular mail. On the upside, it did come with tracking so at least we’ll know for sure they got delivered!

Great value

I actually like that it’s not rigid. It’s just stiff enough for shipping stickers/ art prints without adding too much weight. All envelopes came glossy white and clean. The adhesives were strong. There’s a logo and ‘made in china’ printed on the bottom but I just cover it with stickers. Looks high quality especially for the price. I would repurchase when I run out.

I sell stickers on Ebay and need them to be truly rigid so that I don't have to worry about bending nor do I have to put extra protection. These are super thick. Put it this way, it is stiff enough to hold a standard coffee cup on it without bending. Post office would qualify this as a package because cannot bend more than 30%. Yes these are a little more expensive at .48 cent each but they are quality. Oh and I did the math... buying the 5 pack runs you about $.64 each so stick with the singles or 4 pack. I imagine it is because they have to incorporate the ship price I also got these within 2 days. I am overall very please with this purchase!

I only started buying this around April so I don’t know what the quality was like before that other reviewers dislike how it is now. For me it is sturdy enough to mail out A2 sized greeting cards—I’ve sent out over 100 orders with no shipping complaints. So no complaints from me!

This is the second box of rigid mailers that I've bought. The previous were larger, but of the same material and manufacturer.I use these to mail out paintings that I don't want to be bent during shipment. The mailer itself is fairly stiff (though I include additional shipping material to keep it from bending). The envelope material is a little glossy, so when I stamp my return address on the envelope, I either have to use alcohol-based ink or cover it with a piece of clear tape to keep it from smudging.There is an adhesive strip at the top for mailing and a tear tab for opening. The adhesive is strong, as I've barely had to press the envelopes closed and never have any issues with them sticking.I can fit 2 5x7" pieces of art inside the envelopes, though I usually just stick 1 in with a piece of chipboard to keep it rigid.Overall, for the price, I'd say it's a great deal.

Size is a little smaller than expected, does not fit 6"x8" mylar bags, had to fold them down to fit the width. The outer measurement is exactly 6". However, this does make it the cheaper mailing rate as it fits within the 6 1/8th" allowance. So, this is sized for 5"x7" contents.I am customizing the blank surface for my branding and acrylic paint works nicely on them. I would prefer the craft paper/cardboard look, but the white does show colors on it vibrantly. My packaging looks unique and distinctive. I did stencil on top, and had a little difficulting with the bottom layer of paint not adhering but it worked well with my designs.The mailer is nice and sturdy. I am confident my products will be shipped safely. The adhesive feels secure as well. My items were a tight fit, but worked.

I'm an illustrator that runs an online store for prints/stickers. I use these for my print orders, and I haven't had a single package turn out damaged. The envelopes are very sturdy; enough so that backing board is unneeded, so it definitely saved me some money there. If you're going to be using these to ship photos or anything of the like, I definitely recommend them. I'm on my second order, and I don't plan on buying from anywhere else!

These are very high quality white cardboard envelopes. They keep things firm and protected. They deal well. When more than 1/2 “ of product was inserted, the fold did tear a bit when sealing. Recommend for photos but almost too stiff for additional content.

Excelentes sobres el material es grueso, lo uso para guardar Fotografías además cuenta con adhesivo para cerrar el sobre y tiene unas pestañas para abrirlo rápidamente.

Needed sturdy and rigid envelopes and these are exactly that. It is difficult to find a small size so I am glad to have found these dimensions. Came within 2 days of placing the order. Will definitely purchase again when needed, thank you!

I've used this mailers for years now, especially at Christmas, and they are always perfect. They are so sturdy, the adhesive sticks really well, the price is really great (especially compared to these mailers you can get at stores like Staples) and they come really quickly. I've probably ordered at least 25 packs of these in the past and they've always been perfect. Highly recommend!

I was hesitant to buy these because of mixed reviews, but thanks to the return policy I took a chance and I'm so glad I did! WOW! These are SUPER sturdy. They are solid and well made. They'll be perfect for mailing out handmade cards from my Etsy Shop. As a new shop quality control is important to me and having my item arrive safely is more important than the purchase itself. I have such peace of mind sending my product in these!
