What Make iStick Pico Kit Like A Single Piece?

The top part of the Melo 3 Mini tank is made up of a thick stainless steel drip tip that is supposed to remain cool even when chain-vaping at high wattages, and a detachable top cap that conceals the top-filling system. Just unscrew the metal cap and pour juice inside the tank through the two large side slots, NOT the center chimney. In the lower section, under the glass tube, we have a stainless steel ring that conceals the tank's adjustable airflow system. This particular design element really improves the overall look of the tank especially when it's mounted on the iStick Pico . The two just seem made for each other, and without any visible large cyclops air slots, the tank just seems like it's fused to the mod, like they are a single piece.
