About this item

• 【REUSABLE】When the color turns dark green, it’s time to be reactivated or replaced; Place the silica gel beads in a shallow container and put them in the oven at 250℉ for 2 or 3 hours; If the color does not completely return to orange, sift the beads a little and heat for another hour; Do not heat silica gel to more than 356℉ (180° C) because it will lose its ability to absorb moisture, and destroy the indicating chemicals.
