Under this category you will find base fluids and nicotine shots that are used when you want to create your own e-juices or if you want to fill in your shortfill. Because even though there are many ready-made e-juices on the market, it can be fun to mix your own e-juice and have it tailored to your own taste. What is required to create your own e-juice is base liquid and aroma. Aromas are the seasoning itself, and base liquid is the filling itself. What is required for your shortfill is a shortfill flavor in a bottle to mix with base liquid or nicotine. Base liquids are nicotine-free, and if you would like to make your own e-juice with nicotine, you can buy nicotine shots.
