O.pen ISH cartridges are built with their CeramFLO technology. The use of an all-ceramic atomizer allows for 2x larger hits versus traditional cartridges that use internal wicks. The ceramic material allows for even heat dispersion and more efficient oil absorption as well as tastier hits. Because the cannabis oil does not burn or make direct contact with hot metal parts, the oil is able to vaporize at lower temperatures which result in delicious tasting hits. The all-ceramic atomizer also uses eight oil inputs to fully absorb all oil within the tank, preventing residual oil waste.
