This is Kangertech e-cigarette subox mini starterkit just for show ;). Nice design - simplicity to the point but only one problem it's fcking expensive. And of course the best e-juice out there Fcking flava which is also on the fcking expensive list.
The airflow system design is quite interesting - it's something that i never thought of how they could make it without the juice flowing out from the air holes. It's surprisingly genius design from the inside of the screw. China is the best in the business of making this stuff really!!
