Ẁhat is your rationale for long term storage in the smaller bottles? I've got my long term supply in 1 liter bottles. When it's time to open one I'll divide it into 4 250 ml bottles. Those will be the active bottles for mixing. When all 4 are finally empty I'll divide another 1 liter bottle the same way. I'm doing that to minimize the space requirement. As of now my long term stockpile will fit on my freezer door shelves, space I can live without. I'd like to avoid operating a separate freezer.
On Smaller Bottles...
I like the Concept of Not having to open the Same Bottle every time I need some Nicotine Base.
I would Also hate to Drop a 1 Liter Glass Bottle and Break It. A 125ml or 250ml would be Bad Enough. A 1L and you might see a Grown Man Cry.
Smaller Bottles can also be Easier to Fit into a Freezer. Or at least into Mine.
