Drop the HUMI-SMART reusable humidity indicator card inside your sealed container. When the card turns from pink to blue it is time to change your HUMI-SMART pack.

Simply replace the current HUMI-SMART pack  when the PINK / PURPLE dot on the humidity indicator card turns BLUE.

Please note: When these cards arrive they will be blue. Once you place them in the desired RH environment the card will turn from blue to pink. Then when the card starts turning from pink to blue again it is time to switch out the HUMI-SMART pack. These cards are reusable.
