These 2ml pods are designed to be used with Smok's RPM Lite Pod Kit. They have a coil installation that can be done quickly and easily. Just draw or push the coils into and out of the pod's bottom.
To prevent leaks, each pod includes a silicon cap over the fill port. To complement the RPM Lite Pod Kit's design, a black tint has been added to the pod, although your e-liquid level is still visible.
The package does not contain coils.
