NKD100 Original Melon Kiwi salt is compatible with any non-sub-ohm device. But we highly recommend using it with a refillable pod system. NKD100 Salt is a nicotine salt infused e-Liquid formulated for pod systems and other similar low power devices. NKD100 Salt Melon Kiwi combines the smooth and subtle sweetness of Honeydew, the crisp juicy tartness of a Granny Smith Apple, and finishing with the refreshing notes of Kiwi.
