★ Brand New, Unopened ★ OJIKA Industry Genmankun 4 Low Potential Hydrogen Tea Ceramic Bottle Hydrogen Water 【Features】 The most advanced "thermos" that maximizes the antioxidant power of "tea." You can easily make hydrogen tea just by putting tea in the bottle. It creates tea with a low oxidation-reduction potential by utilizing ions and static electricity generated from the combination of small vibrations of matter, while adhering to the laws of nature. Negative ions overflow from the tea inside the bottle, and as the tea becomes low potential, the amount of hydrogen also increases. By putting tea in the bottle, it transforms into the highest level of "low potential hydrogen tea" in about 5 hours. - Brand: OJIKA Industry - Product Name: Genmankun 4 - Material: Ceramic - Cap Material: Wood, Cork - Color: White - Capacity: 850ml I took it out of the box for listing, but I will send it without opening the packaging.
