1kg of raw nest can only process about 750gm, for example, the 1kg have to remove out feather, sand, and others .Then soak it into the container with water for cleaning and removing all unused parts. After heating and air drying, we will have a nice nest. 75o gm /6 gm=125 pieces, put 6 pieces in a box. We can have 20.83 boxes.
