SAI Premium Black Corrugated Literature Box Mailer Pack of 10-4x4x2 Inches. Cardboard Shipping Boxes and Great Gift Packaging Boxes

Love the size of these boxes, as I’ve been mislead in the past by sellers. The boxes are not even sturdy enough to be mailed. Pretty disappointed in these boxes — too pricey for the quality. Will not be ordering again.I had to tape almost every fold in the boxes for them to stay put, i’m sure it’ll be better with products in the box but just to make sure I taped them. I don’t even think these boxes will be able to support glass or other heavy items. Again, these boxes probably can’t be mailed, they are weak and not actual mailers, they don’t even close fully. I’ll probably have to tape and cover with a sticker and wrap it with twine to ensure safety of the products.5/10, and the 5 points ate for the color & size lmao

Doesn’t come with instructions so I tried to refer to the video, but it wouldn’t load so I got frustrated and figured it out myself. One of the sides wouldn’t snap into place correctly so it just flaps open *refer to the picture I took. At first I thought this was a fluke, but when I tried it on a second box it did the same thing on the same side. I probably got the unlucky batch but it’s nothing a hot glue gun can’t fix! The inside is also a bit smaller then advertised because of how the cardboard folds over. Overall it was a ok. I would not purchase this again

Decent looking box compared the corrugated cardboard boxes I normally use. But price seems awfully high and I have to tape one of the inside flaps down on each box after folded.

There are no printed folding instructions on the boxes or an instruction insert. However, you can figure it out in a matter of minutes. Once folder the sides are very sturdy, however, the cardboard is not as thick as a standard amazon box, due to less internal reinforcement within the cardboard. I would say it feels about 1/3 less thick. Bottom line, if you are shipping light to medium light items this box will work well. Do not count on shipping anything heavy or anything glass without providing some additional rigid protection and decent cushioning material. Overall, for the price it's a good value.

The media could not be loaded.  These boxes are exactly what I needed. I've spent so much money trying to find the right size box in black. They are easy to assemble and arrived on time. I will definitely purchase in the future!

These are my go to boxes for shipping care packages and books. They are super sturdy and provide some measure of water repellent. I mean - don't drop them in a puddle or anything. But, a care package that included sugar doilies got stuck in a rain storm before our mailman came and the sugar doilies didn't get wet. (I also wrapped them in plastic on the inside, but I digress). Seriously, they look awesome, and they protect the things you ship. Worth it!

The pink boxes arrived the next day, as promised.The measurements for the box are accurate as stated in description.The only thing I can find wrong is you can see where they boxes in the clear bag have rubbed against each other. This isn't a problem for me since I know that when I mail them they will show wear, too.The video was helpful for the first time, easy to fold after that.Great box for the price.

I bought these to send out monthly subscription boxes for my business. They will have to work but I am not very happy with how flimsy they are. The are very thin and not great quality. I wont buy them again.
