The Smok G16 Coils have been specially crafted for use with the Smok Gram 16 tank and the Smok Gram-25 Kit. The G16 coils feature a dual coil design which enhances the flavour of your e-liquids, due to their large surface area. These coils operate best between 15-25W, and even below these wattages the dual coil design gives you the most flavour from your e-liquids. This item contains 5x Smok G16 coils.
