TFV8 comes with cotton? I know nothing about coils...

[vaporiser]

I've noticed the TFV8 tank comes with cotton. This is to re-build the coil and make it fresh again? How do I do this?

Go to YouTube and search TFV8 coil rebuilds. Should get lots of hits

This might help

You can only rebuild the RBA though, the other 2 atomisers are disposable.
