528 Custom Vapes started when they wanted a tank that could perform like a dripper. At the time there wasn't such a tank on the market. 528 Custom started modifying kayfun's to get better performance. At the same time, local shops and fellow vapers wanted to purchase them for their use so 528 Custom start producing and selling these modified tanks to customers throughout the world. The demand was so high that they decided to create their own tank, the Monster V2. The Goon RDA Line is a collaboration designed by coil architect Blue Eyed Goon & 528 Custom Vapes. 528 Customs keeps moving forward to keep innovating and bringing better products to the vaping community.
