Starre Pure Sub-Ohm Tank offers a massive 4mL fill capacity and features a SUS304 Medical Grade Stainless Steel construction with anti-corrosive/heat-resistant glass. This top-filling tank stands at 64.3mm tall and is 25mm in diameter, promoting FreeMax’s all-new 0.25 & 0.50 ohm Patented Ceramic coils. Each Ceramic coil is wicked with Japanese Organic Cotton, offering world-class flavor and a truly remarkable performance. FreeMax has tested the longevity of their Ceramic cover coils intensely, proving that each coil can withstand up to 60,000 2-second puffs and can be refilled between 80-100 times before needing to be replaced. Unlike many tanks on the market today, the Starre Pure’s adjustable airflow ring control is located at the top of the tank, providing easy access to two large air inlets for total air flow customization. Each piece on the Starre Pure Tank can be easily replaced, providing a cost-effective alternative to many RDA, RTA and RBA’s on the market today.
