The Joyetech Cubis Atomizer was designed to be more leak resistant than any sub-ohm tank that has ever been created. It does just that with its cup design! The “cup design” pertains to the method by which you fill the tank itself. When you remove the top cap to fill, you will notice that the coil head comes out along with the top cap and chimney. From there, all you have to do is fill the “cup” you are leftover with to the fill line, and then re-attach the top cap. Voila! No spills, no leaks, and a great overall vape.
It is recommended that you use a Max VG blend with this tank
*Replacement Coils for this unit are the Joytech BF*
