The tank Seems like plastic on this one.
I responded to your PM.
Is this the real deal Mini Cobra (I bought it from Gotvapes)? Daniel or Chris can you answer this please. It makes no difference to me either way since I love this thing, just a matter of curiosity.
*edit*
I dissambled it to clean it and the crack has gotten worse. I will look at the links that gave me Nathkiira. Some of those tanks are purty!
