50 Multi Depth White Bookfold 12 1/8" x 9 1/8" x1/2", 1", 1 1/2", 2" by The Boxery

I bought the boxes to mail books and they do the job. It takes a bit of patience to fold on the exact scoring line you need and then hold the box with one hand while folding/taping with the other. But for the money it's doable and worthwhile. I've only used about 5 of them so far so I may go more adept as I use them more.

REVISED 2017: The seller or manufacturer nearly doubled the price from less than $25 in 2015 and 2016 to nearly $50 in 2018.2015 Review: Very useful and lightweight. We use this to ship flexible paper items that would otherwise be bent in the mail. These bookfold cardboard mailers are solid enough to hold one item or 70. Great value!

Great quality. Sturdy, adjustable, easy to assemble, perfect for mailing spiral bound books. Will buy again.

This box is just a box. Some of the quantity I received were damaged but I was still able to use them by putting packing tape over the torn parts. The cardboard seems lighter with less strength than the boxes I purchased a few years ago from another supplier. But, these are less expensive and they suffice. So the price is good, the quality is mediocre, but they serve the purpose completely. What more can I say?

I recently sold 50+ RPG books and these were great. I got a few kudos on the nice shipping job. Never had any issues at the post office with someone questioning "media mail" as they are clearly book mailers! The scored lines make for easy folding. To ship digest sized books I simply measured and with a few cuts, a perfect fit!Some people have mentioned how it's tricky to seal by yourself, I solved that with a little piece of scotch tape across the seam until I can get my big strip of shipping tape down. No issues at all I wish you could buy these in smaller lots as I have a few more books to sell but don't need 50!

These are perfect for mailing books. They have multiple "score" lines so it is very easy to tailor the box to the thickness of the book. Ken

It works great and good thick quality box but you still need to use tape to seal the box. To save time, I will buy the self adhesive ones.

Boxes work great when shipping books in. Like the fact you can change the size of the box for the size of the book or books you are going to send in them. Sure you can use them to ship other items in also. You don't have to keep different size. Boxes on hand.
