Important Notice

We normally list 24 months as the shelf life in our COA, the real shelf life can be slightly longer than 24 months if it's stocked in good condition (bags are sealed enough, away from direct sun-light, moisture and other incompatible chemical materials), but it's still suggested to avoid long time storage.
