When I first started, I tried using a pretty container with plastic, sectioned trays from a craft store. But, it got irritating that the bottles of flavors would turn to where I couldn't read the labels. I didn't see the point of having them all lined up pretty in different sections like that. It was a waste of time and organization.
So, I finally divided the flavors up into categories and
threw them into empty plastic peanut butter jars of various sizes, then put all of it into a plastic container that I could store in the top of my closet.
I think I have 3 jars for flavorings, 1 jar of syringes, bottles of nicotine, PG, and VG, plus 2 plastic graduated cylinders all tossed into a plastic container like this from Walmart:

The plastic container from Walmart was only $4. The peanut butter jars are free, plastic, and see-
through. And, since the bottles spin around where you can't see the labels no matter what you put them in anyway, it's just as easy to see what I have.
Not as pretty, but very practical.
