Going to purchase some glass bottles to transfer some eliquid I received in plastic bottles. Wanted to do this for juice I will be storing for a few months possibly. Just not comfortable leaving it in the plastic bottles much more than a month. Question is should I get cobalt blue or amber glass bottles. Is there any advantage to either. Was planning to get caps without the dropper because of the softer rubber used in the dropper caps leaching. Is this an issue? Also best place to purchase? Was looking at specialtybottle.com
