I've got these in, and they have a sort of cotton on the inside of them.... how do I vape these? Do I remove the cotton? .. it might be a 'wick', I don't know for certain. Do I drip juice into a new one? Do I fire it dry? Let me know!
Also, anything else I should know about cartomizers? I've only used atomizers, which is what I thought I bought... let me know guys!
