yup...Hangsen is the worlds largest manufacturer of e-liquid. there manufacturing plant is in China, but they have corporate office in Poland. i'm not exactly sure if they produce flavors or liquid in Poland, though.
their flavors are sold in some of the largest online retailers, like ECX and BCV. are you in Europe? i'm sure they are readily available across the world. and Hangsen flavors are pretty strong, also. and they have awesome bottles, lol! No, i do NOT work for Hangsen...lol
