Remove the Boost® pack from the clear overwrapping. Take care not to rip the Boost® Pack The pack starts to work as soon as it is exposed to air so don't leave it out. 

Place the Boost® Pack and color-changing Humidity Indicator Card in a sealed container along with your product. 

Replace the Boost® pack when the dot on the Humidity Indicator Card turns bright blue. (The card will slowly turn from pink to lavender and finally to a bright blue—this is normal and expected).
