Easy, Sturdy, Sleek, Great!
These mailing boxes are the real deal, thank you to the video reviewer! I got the 9x6x2 version. Super easy to assemble, super sturdy to be used as actual shipping boxes and very sleek. Exactly as described and pictured! My favorite part has to be the assembly. Unlike the USPS boxes of this size, I’ve never been able to figure out what to do with the “flaps” around the sides for those, so I have to tape all 4 sides together. No problem with these boxes. The sides easily fold and “lock” in place! No extra tape needed to hold things together. I do wish these were a touch larger matching USPS’s dimensions, but that’s ok. Be careful with a similar listing on Amazon. The pictures, price and product are almost identical, but from one of the video reviews, you could clearly see the cardboard in that other listing is super, thin, flimsy and cheap. Those are not appropriate as actual outer mailing/shipping boxes. This one is!

Great find
Exactly what I needed, boxes are sturdy which I wasn’t sure about when ordering, gloss finish, great for some gifts I got that were slate sublimation pictures which fits with like 1/2 in on each side

Perfect Size for Small Business Owners!
I’ve been using the Mcfleet 13x10x3 white shipping boxes for my small business, and they’ve been a game changer. The size is absolutely perfect—not too big, not too small—just right for mailing products securely without wasting space or materials. The white finish gives my packaging a clean, professional look, and the tab locking design keeps everything safe during shipping. Super easy to assemble too! If you're a small biz owner looking for sturdy, sleek packaging, these boxes are a must-have.

Sturdy and elegant
I use these to ship or package glass items for my small skincare business. They are thick and sturdy enough that I've never had a product break during shipping. I have them in multiple sizes!
