Our company started when we wanted a tank that could perform like a dripper. At the time there wasn't such a tank on the market. We started modifying kayfun's to get better performance. At the same time, local shops and fellow vapers wanted to purchase them for their use. We decided to start producing and selling these modified tanks to customers throughout the world. As we kept hand modifying and producing these tanks we found ways to make each version better then the last.The demand was so high that we decided to create our own tank based off of our ideas and vision to push the limits to the next level. And above all else, to give our customers the best possible Rebuildable Tank Atomizer . And the Monster V2 was born. We look forward to keep innovating and bringing you better products in the future.
