Each bigger box contains a top, white box split into 8 compartments and a transparent, bottom one that can be split with plastic "separators." There's one long separator and a total of 6 shorter ones. You can remove any and all of them, depending on how you want to arrange them.
In the area marked by pink I placed 60 2x4 bricks. So, the full bottom, transparent compartment should fit about 480 2x4 bricks. (maybe more, if you remove the separators). I use the top one for smaller pieces and plates.
You can also stack them.
I bought the two 3-story versions. Each one of them has 3 big transparent containers and 3 white ones.
The only flaw - the modular separators are quite flimsy, but if you put the bricks in there, they shouldn't move around.
