The Smok RSST Dual Coil with Airflow Control had arrived at The Vaping Buddha, and we couldn't be more excited! Smok has kept all the great features of the Smok Pyrex RSST- pyrex tank, insulated wick hole and tank, and the innovative post hole catch spring. Now the Smok RSST DC AFC is even better with TWO insulated wick holes and and airflow cap with HUGE vertical airholes that can be adjusted wide open to all the way closed- no more genny leaks! Paired with TVB favorite stainless steel rope and ekowool, no more genisis dry hits either! Drop by The Vaping Buddha and try it out, we have one set up and we think it'll change your mind about tanks :) 615 W Orange Ave South San Francisco CA
