I, too, keep a bag packed at all times with essentials, including a set of hot rollers (which I haven't used in years, but, you never know!). My carrying cases, though, are a lot more primitive than what y'all have described. I've got a bunch of those Clinique bags from different promos and I use one for oral care, one for bath and body, you get the picture. Actually, it works out pretty well because you can fit them into little spaces between shoes or to fill in to the corners, etc. Still, it may not be the most efficient use of space.
