First of all, this product is being offered at a discounted price because it may be cracked, chipped, or stained black with squid ink during processing. Please purchase only if you are comfortable with such imperfections m(._.)m We use the bones of fresh, sashimi-grade Mongol squid. First, we thoroughly wash them with edible sterilizing water to remove slime and ink stains, then soak them in water to remove salt. Furthermore, we simmer them slowly in boiling water for about 30 minutes, removing any remaining slime while sterilizing them. Immediately after that, we arrange them on a steamer and dry them in the sun for at least 3 days to achieve a well-dried finish. Depending on the weather and the season, if it rains and we cannot dry them, we may dry them in a drying room and then finish them with sun drying. As it is something that living creatures will consume, we store it properly. Regarding storage after purchase, please avoid storing it in humid places. If it is humid or wet, it can cause mold. If it gets wet, please dry it in the sun. We will pack it carefully when shipping, but as it is a fragile item, it may chip or break. Please purchase only if you are okay with this. Depending on the stock situation, we will include small pieces or chipped pieces as a bonus. Please feel free to use them. We can also accommodate requests for bulk purchases, sizes, and quantities, so please feel free to comment. #CuttlefishBone #Cuttlebone #CuttlebonePowder #SquidBone #SquidShell #BirdFood #ParrotFood #TortoiseFood #Calcium #Reptiles #Cuttlefish
