The Metal Edition of Fireluke 2 is the updated version of the original Fireluke M, with the TX series Mesh Coils, slide-to-open top fill design, 360 degree e-liquid feeding, patented 90% tea fiber cotton & 10% organic cotton formula, the Fireluke 2 offers a stylistic design and great flavor compared to all the other mesh coil sub ohm tanks in the market. The Freemax Fireluke 2 adopts the newly designed Slide-to-Open top fill mechanism — a simple slide of the top cap then you can fill the tank at ease. The patented Vent Hole design can effectively accelerate the filling process.
