We know the most important part of the ccell cbd cartridge is the coil, which is the key factor that influences whether the
cartridge leaks or not. Most of the factories now packing the coil cotton by hands and which will lead the unstable quality and
the oil leakage rate is high.

reduced the rate of oil leakage and can ensure the stability of quality. As normal the oil leakage rate is under six parts per
thousand.
