The other day i bought my first vaporizer kit. I found a zig zag clearomizer for $20.00 at a convenient store. For juice i figured if it had the zigzag name it probably wasnt very good quality, so i saw a big case with NJOY liquid in it. They had alot to choose from flavor and strength wise. I settled on double espresso 30mg/ml 10ml im confused bacause the only strengths i find on line are 10mg and 15 mg liquid. Is my juice rare or really old? Also is my clearomizer good quality or garbage?
