The Innokin iSub B Sub Ohm tank is a well-designed tank that has a standard 3 ml e-juice capacity, a threaded top-fill system with protection, and the new Innokin iSub B Plex 3D mesh coils. Made of durable stainless steel, the iSub B is equipped with Pyrex glass reinforcements to protect standard 3 ml e-juices with a rainbow tint or an expanded 4 ml juice capacity. In the upper part there is a filling system with a thread on top with automatic protection against flooding, preventing unwanted leakage during refueling. In addition, at the base is a set of bored airflow channels behind an adjustable airflow ring to change the airflow restriction for each hit. Inside the tank is the Innokin iSub B mesh coil with extensive micro-grooves on the mesh heating element to increase surface area and create a better juice flow due to the capillary effect. Using wood pulp and organic cotton as the wicking material, the Innokin iSub B Sub-Ohm reservoir certainly functions well when used in combination with the Innokin iSub iSub B Plex 3D family of 3D coils.
