Thank you for viewing. This is an adorable iron ball in the shape of a tetsubin (iron kettle). I stored it in the refrigerator to prevent rust, but there are a few spots of rust. I intended to make it a habit to supplement iron by putting it in hot water, but I couldn't keep it up, so I'm putting it up for sale. Easy supplementation of essential iron Just put it in a pot or kettle and boil it. It can be used in cooking eggplants and black beans to make them more vibrant. Not for use with direct fire, microwave, oven, etc. Not for use with dishwashers or dish dryers. Composition: Iron Size: Approximately 4.5cm high x 4.5cm wide (maximum) The plate is not included. Rust is not a problem for the product, but If you are concerned, please refrain from purchasing. #HotWater #IronDeficiency #IronSupplementation
