These cartomizers hold 3.5ml of eLiquid in a completely clear tube with your choice of either a blue, green or white LED. Just fill the cartomizer and then vape away, and every time you vape the tank lights up! They come with a bit of primer so we recommend that you give them a good rinse before you fill them. This is a top element cartomizer so the flavor and vapor are absolutely amazing!

• Fits all standard 510 threaded batteries.
• This cartomizer has the new type of seal that does not require a syringe to fill!
• Condensation can form inside the larger mouthpiece and if that becomes an issue simply remove and blow out or dab with a napkin.
