These concentrates are the actual flavour blends Decadent Vapours use to create their ranges of e-liquids. All are PG based and have been third party tested for diacetyl and acetyl propionyl. All supplied in a plastic bottle with dropper, with the exception of the Absinthe, which is supplied in a glass essence bottle with separate glass dropper.
