I was reading through the forums and came across the pyramid tea bad mod for cartridge filling. I went to my nearest grocery store and sure enough I found Lipton pyramid tea bags. Came home and made one to go in my cart just as I had seen in the videos that I watched. This is pretty good... I like it a lot..it does make the e-liquid have a better taste. I was wondering if anybody else has tried it? And what your thoughts on the PTB mod were?
