The top has 32 compartments for polishes. It fits all size polishes I of course fit more then 32 by putting my strippers upside down and I fit 3 in each slot.
The bottom is divided in 3 sections. They are very wide and spacious I can fit all my tools and supplies without a problem.
I absolutely love this train case one negative thing is that after its loaded it is extremely heavy so I might just keep the smaller Caboodles one to take when I don't need that much stuff. Ok till next time!
