The OBS Cube Mini Replacement Coils are designed specifically for use with the compact, portable, and surprisingly powerful OBS Cube Mini 1500mAh Starter Kit with Cube Mini Tank. Available are the S1 0.6 ohm Mesh Coil that OBS has optimized for sub-ohm use with standard e-liquids that include freebase nicotine. Also available is the N1 1.2 ohm Coil that is optimized for use with nicotine salt infused e-juices to provide a smoother throat hit at higher nicotine levels. These coils are the perfect way to get the fresh experience you desire from your OBS Cube Mini Kit. Always be sure to let your vape juice fully saturate the 100% Organic Cotton Fiber with the coil head to avoid burnt or dry hits.
