^{Q:What is oil coil separation?}

^{As its name implies, OCS means the oil and coil are separated until initial activation. There are two advantages for doing so. In a word, it prevents leaking 100% while maintaining freshness of the e-liquid until the very last puff.}

^{Firstly, before using the disposable pod, OCS avoids any chemical reaction between the oil and the coil, thus maintaining the freshness of the e-liquid.}

^{At last, it is inevitable that cartridges will have some degree of leakage. Oil Coil Separation perfectly solves the problem by containing the e-liquid apart.}
