12 1/8 x 9 1/8 x 2" White Easy-Fold Mailers

Yes, they are very thin -- 1/16" thin, to be exact! In fact, if you squeeze too tightly in-between thumb and forefinger, you can actually make an indentation and crush the fluted cardboard inside that comprises the corrugation in-between the very thin outside sheets. Thank God that you get the side flaps, or this product might not give the support needed during shipment. I was planning on using bubble wrap inside, but now I'm thinking I might need more cardboard support, too. That will negate the money I thought I was going to save by using these boxes to mail comic books, instead of envelopes with two sheets of cardboard, which are twice the thickness of these and give all the support I need, but are twice the cost of one of these boxes.The scores where you bend the boxes to adjust the height have very shallow indentations and are very hard to see and feel. This would have been much better with perforated scores. So, what you need to do is lay the open box down on a stable horizontal surface and lay a straightedge like a sturdy ruler in front of the score you want to bend, and then it's much easier. The boxes seem to want to bend at the most shallow depth of 1/2", so be careful of that if you want a deeper box.The thinness will reduce some of the weight and lower the cost of shipping, so that is a plus. But I do wish that they were about twice as thick as they are. Once the box is folded, it feels sturdy enough, but let's see if it survives the rigors of a trip through USPS land. If I don't get any complaints, I guess it will be okay.

I mail out quite a few books and these boxes work perfectly! I have purchased these several times because of the price and the convenience of using these boxes.It is true that it isn't always easy to get it on the exact fold that I want the first time and as a result the box isn't always perfectly straight when I am done, rather curved on the sides, but this doesn't take away from the functionality. I also always wrap the books in bubble wrap first so they are a bit more protected. I have never experienced a problem with damage to the book inside during shipment and for this reason, these boxes do the job just fine.I have bought similar boxes, that are more easily folded, but they have also been more expensive. I will continue to stick with this box as long as the price is right!

Worked perfectly for the job I was doing. I had to add some half-inch styrofoam cuts to firmly package a plastic ring bind personal book made from a color laser printer of less than 1 inch (final 9 X 11 inches X 1 inch). Post office had no comparable option. Nice to have an option of ordering less than 100 at time, at less than a dollar apiece. I was able to order 50, rather a minimum quantity of 100 from someone like U-line (a bit cheaper by quantity). The only drawback the length of time to recieve (1 week) for free shipping, but that wasn't a biggy. Apparently, orders are produced upon order rather than shipping from a preproduced inventory, which is similar to a book on demand option.

I'm very happy with this product. I sell books and these are definitely perfect to wrap them in for shipping. Make sure to take your time and fold on an actual line so it works well for you, otherwise you'll get those skeewampus knarly bends that make you grit your teeth. For the price you get a great product.

I think these are great. They are a little thin but I've not had any trouble with them as other reviewers have mentioned. I'm not sure I'd trust them to an item that I didn't want crushed. I really like that the size is adjustable. I'd purchase them again, but won't need to anytime soon. There are so many in the box that they should last me quite a while. I was hesitant to purchase them because the shipping was so high, but the box is very large (about 2' x 2-1/2' x 12") and I'm sure part of the cost of the boxes is rolled into the shipping. All in all it's a pretty fair price considering there are 50 boxes.

Works well forsending books

I bought these to ship small hand made trinkets. These were the smallest size boxes I could find at a reasonable price. I got what I paid for......They are not good for anything fragile or delicate unless you want to double them up. I am sure they are just perfect for shipping books (which is their intended purpose)Then the shipping......all they do is bundle a pile of boxes together with straps and slap a shipping label on it. Many of the boxes were damaged by the bundling straps. Additionally, the bottom box got filthy in transit, and the top box was useless because of the shipping label stuck on it. It is a very odd thing for a seller to not package something that was purchased. Imagine if you bought a shirt online and the seller glued a stamp right on the front pocket and threw it in the mail.

Does exactly what it says on the package. I've used these to ship a variety of books, all different sizes. Thus far these boxes have fit every book they've come across.They do need to be reinforced in several areas to prevent opening if you plan to ship them. However, accounting for the extra tape that is used they are still a great bargain.
