Airistech VE9 Slim Empty Refillable Cartridge Tank For THC & CBD OilsThe Airistech VE9 Slim Oil Tank is perfect for those looking to use CBD and THC oils with their vape device.

This will allow the oil to adequately saturate the atomizer. The rate at which the atomizer will saturate will depend on the viscosity of the fluid being used. More viscous fluids will take longer to saturate.With the Airistech VE9 Slim Oil Tank its available in two sizes 0.5ml and 1ml oil capacity.
