I felt comfortable packing heavy books and supplies in these boxes for moving

This is a great value pack.

The quality of these boxes is good, they are a good thickness and would protect your (well-packed) belongings in a normal move

These come shipped in fairly large flat box that makes accessing the packing boxes very easy

The boxes are not the most heavy-duty, in that they seem to be lighter weight cardboard than actual banker's boxes (used at banks/ financial or legal institutions for masses of paper records), which need to be sturdier for the weight and use requirements, but these are definitely good for home use and general storage, so that your packing stays neat and organized

I bought these wanting to do a better job packing than last time I moved (boy was that a nightmare).

Nice and sturdy, I would recommend these for packing heavier items like books and dishes

These bankers boxes are a reasonable quality, and come shipped together in a convenient large flat pack that provides 30 boxes and lids in the three sizes listed (i put pics w the dimensions of the small, med and large as printed on the side of the boxes themselves, next to the assembly directions, and a pic of the assembled small box)
