I know that I mentioned that I store mine in 100ml bottles but I just realized that I'm using the 120ml's(sorry, brain cramp)instead. It takes 8 of these filled to the brim to hold 1 liter of nic base. Here are the ones that I use...
120ml Cobalt Blue Glass Bottle
I then wrap them in a double, folded paper towel(protection if dropped), put them in a ziploc bag(push out as much air as I can), then put them into a plastic coffee can. Individual bottles as well as the coffee cans are labeled and dated. Into the freezer they go.
