From what I can tell from this video, those coils are propietary to just that tank.
You are using what we call "old technology". It may be time to change to something more modern.
What type of battery device are you using? In the video it looks like he was using an Ego stick battery. Those are still around, but they are getting harder and harder to find as new techology replaces the old.
If you like your current vape, you should look for what we call a MTL (mouth-to-lung) tank. Something like an Innokin Zlide, Innokin Zenith, or Aspire Nautilus. These use "higher resistance" coils similar to your SMOK and can be used with a low wattage/voltage battery device.
Battery devices such as the Innokin Adept, Innokin Kroma, or Geekvape Aegis (Mini or Solo models) are popular for your style of vaping.
