We started making E Liquid in 2012. And that's when Thunderhead Vapors 'Artisan' branded E Liquid began. The E Liquid flavors have evolved. Some were retired to make room for the new. While some have been with us since the beginning. One thing that has never changed is our commitment to provide the best E Liquid and value possible. The Thunderhead Vapor Artisan E Liquids are a 50/50 PG to VG blend. Strong on flavor and throat hit while still plenty capable of producing thick clouds of vapor. The 50/50 ratio is ideal for broad clearomizer compatibility. Whatever device you put Thunderhead Vapors Artisan E Liquid in, it'll perform!
