All of our eLiquids are designed to be expertly balanced all-day vapors that will not overpower or go flat halfway through your tank. Both S.A.O. & Spectrum Vapor are handcrafted in small batches in St Augustine, Florida, and every batch of eLiquid is tested for consistency to make sure that you are receiving the highest quality product available. You will find no artificial colors or dyes in any of our vapors. And since our customer’s health and safety are our top priorities, we also test each ingredient to ensure that none of our eLiquids contain diacetyl or acetyl propionyl.
