From their website:
"100% USA Manufactured & Bottled. This is a PG/VG Blend, and both are USP/FCC Grade. L-Nicotine is sourced direct from Belgium & the rest of the ingredients are sourced from the USA."
...and-
along with a small handful of other vendors, puresmoker has been quite transparent about their liquid and how they make it - I believe there are videos of them in the lab.
That's part of the reason for the slightly higher price... (unless you
buy bulk)
I have had a handful of flavors... and a couple are in my top 5... good stuff... worth the coin.
great service... great products
