SKE Crystal Refill Pods are replacement components designed for use with specific rechargeable electronic nicotine delivery systems. In the United Kingdom, these products are subject to the Tobacco Products Directive (TPD), which mandates specific safety standards. These include a maximum tank capacity of 2ml for active e-liquid chambers and a maximum nicotine concentration of 20mg/ml.
The hardware utilizes modular configurations, such as the 4-in-1 system which houses multiple 2ml pods, or the CL6000 system which utilizes a 10ml reservoir to replenish an internal 2ml pod. These designs are engineered to be closed systems, meaning the pods are factory-sealed and not intended for manual refilling. This design choice is intended to prevent leakage and ensure consistent delivery of the nicotine salt solution
