Hi, I ordered my Green Smoke kit when I first started vaping. But I've moved on to an iTaste MVP and Nautilus tanks and I'm about to get into RDA's. Anyways I wanted to get some use out of the batteries. I was looking to find cartomizers that I can refill myself with e-juice that will fit onto the Green Smoke batteries??? I also figured that would be a good way for me to sample flavors. Anyways I'm not real familiar with cartomizers so I was hoping I'd find somebody on here who has done the same. Any help is appreciated. Thanks.
