How to Use It
Ensure the bag is properly sealed at the block bottom before filling
Fill the bag to the desired level without overfilling to maintain seal integrity

Store filled bags in a dry, cool environment to prevent moisture absorption
Use only for dry, non-perishable food items as the material is not designed for wet or high-moisture content
