@NicotineRush - I'd suggest that you go to a Harbor Freight store and check out the Store House brand storage organizers. They're the ones that are black and bright school bus yellow with clear lids. I've got in excess of 140 different flavorings, and I absolutely
love the 2 types/sizes I use for storing the vials and/or bottles of flavorings that are less than 4oz (120mL) size. (My 4oz. and larger bottles go into 1 Priority Mail box and are used to refill the smaller vials and bottles.) The organizers have several different types and configurations, with a variety of sections and dividers that you can customize to suit your needs. The smaller of the 2 styles I have is about 17" long x about 6" wide, and is deep enough to hold 30mL bottles with no problem. It's usually $4.99. The larger style is about 17" x 13" and is the same depth. Runs about $9.99-12.99 depending on if it's on sale or not.
To help me organize and find specific flavorings quickly...I used a paint marker to number the lids of
each flavoring vial or bottle, as I bought them. I taped index cards on the underside of the lift-up lid on the storage cases, and wrote the numbers and names of the flavorings on them. All I have to do is get out a recipe card (which has each flavoring + its number on it), and pull those numbered vials or bottles from the storage cases. Makes it easy peasy putting them back in the right place when I'm finished, too!
ETA: Because the storage organizers aren't really deep...they'd also store
very easily under a couch, bed, etc. when not in use. So there's no extra space taken up by them. Their lids close and snap shut so nothing can get into them, too.
Then I would have to have about 5 of those for all my flavors
