Engineered for use with the OBS Cube Mini Tank and KFB2 Kits, the OBS S1 & N1 Replacement Coils deliver exceptional flavor clarity and reliable performance. Available in two distinct versions, these coils cater to both mouth-to-lung (MTL) and restricted direct-to-lung (RDL) preferences.
Key Features & Design Philosophy

Versatile Coil Options: Choose between the high-surface-area S1 Mesh for rich vapor and regular e-liquids, or the N1 Standard coil for tighter MTL draws and nic salts.

Optimized Wicking: Built with high-grade absorbent cotton to ensure rapid e-liquid saturation and consistent flavor reproduction.
