Egg-shaped iron balls are perfect for iron supplementation. When placed in boiling water during cooking, they not only provide iron but can also be used to color eggplants and beans, remove sand from shellfish, and reduce chlorine odor. I purchased this over 10 years ago and it's been sitting in the back of my kitchen. I might have used it a few times right after I bought it. For reference, I've included a photo with a smartphone for size comparison. I hope that those who understand it has been personally stored will consider purchasing. - Product Name: The Iron Egg - Purpose: Iron supplementation, etc. - Shape: Egg-shaped Thank you for looking.
