Hello. I'm new here and i see that nobody opened a new kanger coil without breaking it. I wanted to rebuild my kanger coils and start searching forums and you tube about a metod to open this coil but i found nothing. So i had to use my own brain 
.
I managed to open the coil doing this :
1: removed the silicone rings and insulators and pull out the old coils.
2: put a 3 mm bolt inside and hit easy a few times with a hammer.
3: is out. Now put your new coils inside, test and put the chimney back. Use a pair o pliers and squeeze the chimney and the base of the coil togeder.
4: put all the silicone insulators back and you have the new kanger coil rebuild.
I hope i helped with this and maybe someone can tell me how it works with cotton.
Have a nice day.
