The carts that came with my cig have a little foil cover on them and it appears as though there is a little poly below that. i am curious as to what will be the best way to refill them and what wicking material and how much to use. it is a micro. i have some halo coming that i am real excited to use and want it to work a sgood as possible. thanks in advance. i am a 3 day newbie. also these carts are so small it seems like i get the equivelent of one analog will halo juice last longer?
