I just called 'em and you're right. E-Cig Express does rebottle from bulk stock.
That makes this even more amazing... Geez, I thought these were FA factory bottles!...
Props to them... I would compliment ECX on their quality and safety.
Notice the child-proof, color coded caps, the clear plastic wrap over those high-end light blocking bottles... the 31 drop/ml tip...
This ECX bottles are hands down the gold standard in safe flavor packaging.
The tip can easily be removed w/ a small plier or (down in the groove of) a tweezer, but why?...
These tips are quite accurate and a huge help for test recipes and smaller batches. Just count the drops... no syringe necessary. Takes just a couple minutes to whip up 30 ml of juice now. And no clean-up!

And for equal time, this is the Mama Js Juice...
original flavor packaging...

I think I prefer the ECX bottles over the Mama Js simple (non-PTFE) plastic bottles.
These are good for juice but in my experience, are not desirable for flavorings.
