The SMOK NORD 2 Replacement Pod is compatible with NORD & RPM coils, offers a large 4.5ml tank, and allows you to vape both regular & nic salt e-liquid. A nice feature about the NORD 2 is that you can replace only the coil when needed so the user is not required to dispose of the entire pod; this results in much less wastage & expense long-term. Available in packs of three, the large tank capacity of 4.5ml pod is also impressive for this compact device and features a well-designed mouthpiece.
