PorousQuartz® is a novel high-performance porous glass for frangrance with the highest purity and precise structure made by state-of-the-art technology.
A large amount of essential oil can be loaded owing to its numerous fine pores exceeding 80% enabling prolonged retention and sustained release. Furthermore, the opaque appearence of PorousQuartz® makes a dramatic change to transparent when the absorption of oil is complete.
Repeated use is fairly easy, you can just add oil when the fragrance is vanished!
