My selection is growing substantially and I’m in need of a decent carrying case for the 30ml bottles.
For those who haven’t seen the other similar thread, Four-5ml to-go’s fit nicely in the small plastic Q-tip travel cases that you can find at Target, but I have yet to find something equally as snug and safe for the larger glass bottles.
Please share where you store yours and/or how you transport them.
I don’t transport mine. Well, I have twice when I was meeting people an hour plus drive from my house, then I just put them into a narrow Ziploc and tossed them in the front seat.
I’d look at double-stack .308 or quad stack 7.26/5.56/.223 mag pouches if I were you, could find some cheapo ones that would be terrible for real use for magazines that would work well for bottles. Like http://militarygear.com/elite-survival-systems-molle-assault-rifle-double-mag-pouch/coyote-tan?utm_source=gs&utm_medium=sce&gclid=CLDL9ci707oCFapDMgoduwgAgg but find some airsoft cheapo’s on eBay or an airsoft supply place.
Something like this would be nice Amazon.com: 30ml 30-Bottle Essential Oil Carrying Cases hold 30ml bottles - Fuschia w/Soft Pink interior - 5" high: Health & Personal Care but the diameter is going to be wrong. You might also look at WWII surplus Garand cartridge belts, maybe (don’t think they’ll be tall enough).
Not exactly a carrying case, but I store mine in this: NEW LOCKABLE PLAIN WOOD WOODEN BOX DECOUPAGE 29 x 25 x 15 cm (P29/15) CRAFT | eBay
Whenever my flatmates walk into my room, they beg me to tell them what’s inside 
Awesome suggestions, guys, thanks. Especially the Fuscia one…
I’ve been using this
Brooks D-Shaped tool bag | wallbike.com
with a zip-lock bag inside, so far just for To-gos. Don’t know if the 30 ml bottle will fit, but I will have one today or tomorrow to test.
The bag has attachements for this
Brooks B.67 saddle | wallbike.com
together, something like this, when I’m using the bike. Otherwise I just stick it in the center-console in the car.
Also contains glass vial with daily supplement pills listed in my journal, cash/cards, and a very small cell phone.
