These are my favorite mailers.  I love the zip strip and they weigh less than the manilla mailers I used to use.

Arrived quick and were a hit!  Love that they had a zip strip that had adhesive on them

I don't actually use these for shipping.  I have a thermal printer for most of my business mail and I use the smaller size 2 x 4 Avery labels for my personal mail.  I primarily use this for listing contents of boxes that I have packed in my attic and garage so I can tell at a glance if something is in that box or not.  I also plan to print small size photos of the contents before taping it up.  There is enough room on the page that I can print at a point size that I can read at a distance without having to open the box or pull it from the bottom of a stack unless I know that it contains what I am looking for.  I really like that I can use either my color laser or ink jet printer for these.  If the box is going in the garage, I will use the laser; inside the house, I'll save money on ink and use the ink jet.

I use these almost every day in my Etsy business of paper and party supplies. I can ship gift tags, confetti, cards and more in these and even slide a piece of cardboard cut from a cardboard box to add support. I write the address on with a permanent marker and my own return address labels stick nicely. The best part is the seal on the back that allows me to ship via USPS first class letter rates. I do print my own Thank You 1.5 round stickers to cover the silver seal on the back just in case the USPS clerk wants to question the clear-clasp postage saving feature

I love these mailers! my customers never complain about vinyl damage. Not even once! Be sure to pad properly.

LOVE these little bubble mailers. I purchased these & the Fu Global 4x8 stripes & these seem to be just a tad bit thicker (as far as built in bubble padding) I still use xtra bubbles when shipping glass tho. If shipping small items these are as good of a price as non padded poly mailers in Ebay. Note the size though - item you are shipping needs to be small! Works perfect for roller ball bottles, Eyedrops (15 ml dropper bottles) & things around that size.
Update  The photo is 50 of the banana 4 x 8 bubble mailers & 50 of a different design 4 x 8 bubble mailers. You can see how MUCH thicker the banana mailers are. They offer the most padding out of any of the 4 x 8 designer bubble mailers Ive. tried, & they are the cheapest?!? Go figure!

Love these padded mailers. Use them all the time.

Love the pale pink color of these. I sell some of my families used clothes on Ebay. I am so tired of plain white mailers. I was so happy to find these pretty pink one's. They work great, so issues with them at all. I would definitely buy them again. I would love to see even more variety of pretty mailers, especially holiday themed ones. Thanks for this great product!!

I use these quite regularly. While I typically use USPS Priority Mail Padded Flat Rate Envelopes, you can only order them 25 at a time from the post office so I typically run out and have to use these. At about 20 cents each, they are dirt cheap. I also use them when I need to ship items via first class mail or UPS or FedEx. The adhesive holds well and they are durable. I never tape over them, I only use the self adhesive to seal them and have yet to have any issues with the first 200 I ordered (just recently used the last one from that box). These get used for items weighing an ounce all the way up to several pounds and they still hold up.

EDIT: Still give it 5 stars but wanted to comment that I did receive a batch that had about 50% of them cut wrong or sealed wrong or something. Instead of having about a centimeter of sealed border on the bottom, they would have about a millimeter or less. They would all tear open when you used them unless you taped the bottom. Contacted the seller (manufacturer?) and they immediately sent replacements. I mainly mention this to let you know that the company stands behind its products so if you're thinking about trying these, don't hesitate. Give em a shot and you won't be disappointed.

These are great mailers.  They add very little weight, but are incredibly tough and durable, even the USPS can't seem to damage them.  The price is a solid and getting them in 2 days was great.

I have to say, I was pretty pleased with these. The price was low enough that I expected them to be of poor quality, but these have worked great--I mail comics and artwork all over the world, and these opaque sleeves let me cover whatever crazy packing job I've done and make the envelope look professional. Plus a nice even surface for a shipping label. I'll be buying these again in the future!

Best mailers I've gotten so far on Amazon as far as quality for the price.  Excellent, will repurchase!

If you send a lot of DVD's, video games, etc. in the mail these are great.  Just cut them in half and they are the perfect size for shipping something of that size.  Highly recommended!

Adorable stationary! This brand is one of my favorites. I wish more people would be excited about snail mail! I definitely recommend this.

I found these to be good mailers for the DVDs I have sold on Amazon. Unlike other reviewers, I had no difficulty in inserting a DVD into the mailer and no trouble with sealing or anything. Apparently all my mailings have arrived in good condition because I have not heard any negative feedback about them. Some people complained that they only received 24 mailers in their box, but I received 26, so I'm happy.

These are perfect for mailing photo's. The price makes these very affordable. The easy open strip works very well also.

I feel like these are a bit smaller than the listed size.  But with that said the quality is very good and they will work for what I need them to be.  I used these mailers to ship clothing and small plush items on ebay and they always hold up very well in the mail.  Occasionally I will double it up just to ensure a safe delivery but after a couple hundred shipments so far I haven't had one complaint of transit damage due to a poor quality bag.  I would definitely recommend these bags.
