Maybe milk crates or those white plastic mail bins we have in the states. I found a couple shallow plastic "dressers" at the dollar store the other day. Unfortunately I don't think I could stand up a 15ml bottle in the drawers. Still if you don't mind going horizontally it could work.

OR!

You could super glue some caps to a 2x4. Then just screw your bottles in to the caps as you go.

I've always kept mine in paint pot racks on a bookcase, but don't really like it (I'm not big on the idea of displaying my stuff).

So, recently I've been thinking about picking up a couple of those makeup cases - the type that look like a more square cantilever toolbox. Might be worth a look.

Lowes, I think has a new roller box with a fold-out table thag looks pretty cool. Only downside (other than $80 price, I think) is no storage on the lid. Honestly though, are you mixing that much quantity at a time that you need to haul around gallon jugs? I think most of us that have been at it a while have smaller bottles for mixing, and we just refill/top off as needed.

maybe something like this?

I use a tool box for my flavors, cotton, wires, coils, syringes, blue screwdrivers, spare RDA, etc.

I use a lunch box for my graduated cylinder, funnel, containers, lids, nicotine, mixer, etc.

My VG comes in a gallon jug and rests beside the others.

Images are similar to mine but not exact. Mine are red.

I currently use an antique hard shell luggage case I got for cheap at an auction with lidded plastic trays for the liquids. Seems to work real nice and keeps everything separate and easy to find.

i use a coleman cooler to store my stuff, keeps all the smells in too

Nail polish organizers

I'm interested in whatever answers you get, too. I 3D printed a little rack for vials, but I don't buy vials anymore. Right now, the rack of vials and all my bottles are just thrown in a drawer out of the way. I already had to look through them to find a flavor, so whatever.

I'd really like to see how people store their bottles, besides on a shelf.

E: Hey this looks right up my alley.

Steamer trunk?

I store all my flavors in a plastic tackle box along with my scale. I have a spare chest freezer that’s been converted for home brewing purposes for my pg and Vg

I use an old roll-around toolbox. Works great. Roll it out when you need it, back into the closet when you don't.

I bought one of these, into which I put four of these to hold flavors and wire and other such things. It also has room for my scale, my Brother P-touch labeler, two gallon bottles and two 16 oz bottles, and my binder of recipes. It sits under my desk until it's time to mix/build.

Here it is boys and girls! My new storage solution! Thanks for everyone input!
