SMOK LP2 Replacement Coils is specially design for SMOK RPM 4 Kit. It is an upgraded version of LP1 series coils, retaining the leak-proof structure and optimizing the internal heating elements. The SMOK LP2 coils have been designed for flavor, vapor, and an all-around fantastic vaping experience. LP2 Meshed 0.23ohm DL Coil - Work on a leak-proof vaping experience. Direct to lung vaping. Enlarged contact area for huge cloud production. LP2 DC 0.6ohm Coil - Work on a leak-proof vaping experience. Dual coils for high-quality vapor and flavor. Each coil in this series uses 3 silicone rings to provide tightness. The color of each silicone ring is the same. When inserting the coil into the pod, the added silicone ring on the bottom of the coil would fill the gap, effectively stemming the liquid leaking from the pod that results in a messy vaping experience or dirty hand. The internal heating wire of the SMOK LP2 coil has multiple honeycomb round holes. When the meshed coil gets in touch with the saturated cotton, delightful taste with smooth flavor and rich vapor arise spontaneously.
