I only make small bottles, but my working batch of nic is a 15 mL bottle for 100 mg or 30 for 36 mg. Usually not even filled to full. For me, 60 mL would be a good freezer bottle because it would take almost a year to use up, but you may use a lot more. Just saying, if you're thinking pulling a 60 or 120 mL bottle out of the freezer and working straight from it, I wouldn't. Just don't need that much out and it's safer. The
only time I use gloves is when dispensing out a new portion of 100 mg working nic. Right now, I have a 1L plastic bottle (~25 years for me) in the freezer and no plans to break it up until ready to break the seal, which will be at least 6 months from now.
RE: ordering flavors, there are certainly flavors worth trying as single flavor mixes, especially if you drip. But the idea of looking at recipes first is still a good one. My first order I didn't get that much base as it seemed huge enough,only to realize that if I made a single flavor mix of every flavor I bought, I'd only be able to make 3 mL each
