Vaporesso® XROS 3 Mini Pod Kit. You can also find MTL (Mouth To Lung) style XROS pods which are all available from the Vaporesso XROS range, if you prefer a more discreet amount of vapour. The XROS pods feature a top-filling design and are easily refilled via the filling port located underneath the mouthpiece; you don’t even have to remove them from your device when refilling.
