I use the cubes, but not the folders. With the TSA pawing through our stuff, I like having my things in tidy containers. Makes it harder for stuff to be stolen!

I also use some RedOxx small bags including the Nomad inside my RedOxx carry on bag (in the same color as the carry on bag) to make it harder for things to vanish.

Anything like an IPod, expensive glasses and/ or camera I really bury behind a lot of zippers and clothes.

I lost a bra, a BRA! to the TSA! Creepy!
