The Vandy Vape Capstone 24mm BF RDA is the latest masterpiece made in conjuction with Vape Happy, featuring a unique capstone build deck with spring-loaded action working in conjunction with the waterfall squonk action and Ramp Airflow System. Measuring in at 24mm, the Capstone RDA implements a special grooved texture top cap with stunning impression that truly stands out, with the optional Frosted PC Comp Cap for more subtle use. The Capstone RDA implements a special spring-loaded build deck with an intuitive design in which an expanding pyramid-shaped capstone can be used to sandwich the coil leads. It is properly secured and fastened via a single vertical knurled at the very top. After setting the coils and cotton, the Ramp Airflow System allows for a concentrating air path by creating an inlet of desired airflow via trapezoidal slots at the base. This produces an astonishing vapor production while maintaining high-level for flavors. The Vandy Vape Capstone is also great for squonking due to the design of the build deck, creating a waterfall action in which the squonked e-liquid cascade down the sides of the internal capstone onto the wicks.
