It holds 52 CPCs, or 53 Paulsons, or 54 casino-used Paulsons (or China Clays, I guess) per row.
In the middle, as soon as you take out (with just a bear hand) the stupid dividers, there's room for 4 soft tubes (good only for in-case storage, exactly).
Each tube can accommodate 26 CPCs or 27 Paulsons or even 28 casino-used Paulsons.
Only viable option besides Pelican-type outdoor cases. And it doesn't need racks.
