EDGE is the 1st SteamTuners RTA and features a unique Deck design with one mission, to boost flavor. Coil placement is a breeze and with unlimited space for cotton installation, EDGE is one of the simplest and fastest atomizers to build. It features a top-fill mechanism with one of the simplest, fastest and smoothest refills you will ever experience. In the heart of the juice control, EDGE has a unique ULTEM Inner Sleeve that doubles as a heat reduction element and a wicking assist marker. AirPins, which can be swapped anytime in seconds without opening EDGE, offer an ideal airflow feeling for every preference, from MTL to DL.
