when I purchase a quantity of unflavored NIC, I (wearing gloves, on a tray, in well ventilated area) separate it into smaller amber glass bottles and store in a well labeled brown bag in the freezer. I do not have kids to worry about, and my pets don't go into the freezer, but by putting it in smaller bottles I only expose a small amount to air at a time. The rest stays sealed and safe in my freezer. I also label each bottle with the NIC amount, pg/vg and date of purchase and date of re-bottling.
thanks for a great contest Dawn, some great recommendations here!
