I'd like to sharing a newest product: MyJET Express Pack (with open unfilled e-juice pods): $22.49

It is a new flat device that is simple to use and effective. It is a semi-closed pod vaping device. A 350mAh built-in battery powers a cartridge-inspired juice reservoir and a coil with a resistance of approximately 1.2Ω. Further, the wick is not silica as was used in the first generation of devices, but cotton for a better flavor and no nasty dry hits. With novel design and ergonomic style, it will be more fashionable and popular. 

Features:
Refillable Pods
Slim and Chic
