These do seem thinner than the older version 03325. Two main problems: 1) the perforations are not complete enough causing the boxes to bend when separating them and 2) they tend to crush when stacked more than four high. A plus: they are fairly easy to assemble just do it slowly!
Bought two kinds of boxes. The 10 pack and the 15 pack. Using to move. Put lighter stuff like clothes in the cheaper boxes books and kitchen things in the other boxes Both work3d well. Reasonable prices for both . Good deals both.
Reinforced bottom don't have to tape them together has handles perfect size for items too heavy for larger containers easy to label price can't be beat!
Occasional use will be all these can stand. They are rated for several hundred pounds but they can’t take being stacked more than three high if full of books.
Good size for any number of items to store. I thought 1 step was left out of instructions but was easy to complete anyway due to the pictures. I would recommend.
