Everything is made by hand and in very small batches. As you’ll see on the bottles and packaging label, all numbers match and the batches generally consist of 275 bottles per lot. they invested a lot of time and money in their facility and in the flavours. As a matter of fact, the first five offerings (Signature Series) were in development for about six months before being released. Later, the second five (Mixology Edition), was in development for even longer. They are perfectionists and refuse to allow any liquid to leave their facility before it’s absolutely perfect. Using only USP / food grade ingredients and the best premium pharmaceutical grade nicotine, only the very best ingredients sourced both domestically and locally, all liquid is made in-house in the state of California. All blends result in a 50% VG / 50% PG combination and come only in 30ml bottles. Flavours are extracted from actual base ingredients and each flavour comes in 0mg, 3mg, 6mg, 12mg, and 18mg nicotine doses.
