brain bag: size of compartments?

[Packie]

Hello,

The external depth of the Brain bag is 9'' and I guess that stands for the depth of both main compartments + the depth of the external pockets. But, what is the actual internal depth of one main compartment?

[Joy]

The two main compartments are exactly the same size.

[Packie]

Yes, but what is the internal size of a compartment in inches?

[Joy]

I think that the 9" is roughly the total depth of the two main pockets, so roughly 4.5" each. Which doesn't sound big, but they are really, really big.
