Each pack contains 2 coils
2 Strands off wrathful wire fused with a third strand of wrathful wire giving high volume of cloud and wicked flavour. Best use is on a mechanical device but if your regulated device can handle a low resistance build then they will work great. A good knowledge of ohms law and battery safety is advised. No responsibility will be taken for damage or harm incurred due to poor installation and maintenance of these coils.
