I am selling these because I have accumulated too many through a subscription. WOX® oxygen-enriched water is a new type of product designed to replenish the body with oxygen by drinking it like water. Dissolved oxygen in the water is taken into the body along with the water. The ingredients are only water and oxygen, and it was developed using original special technology to encapsulate oxygen molecules with water molecules. It has obtained a "substance patent" in Japan, the United States, and China, which is considered difficult to obtain. (A substance patent is a patent granted to a newly created substance.) In addition, it has also obtained "manufacturing patents" and "measurement patents" for measuring oxygen concentration in Japan, the United States, and China. The new substance name is "oxygen inclusion hydrate and aqueous solution containing the same." 【Part 1】 Contains Oxygen Hydrate. 【Part 2】 Oxygen can be replenished along with water. 【Part 3】 Oxygen does not escape for over 10 years (maintains over 200ppm). 【Part 4】 It is the world's first product whose oxygen concentration does not change even when shaken, heated, or frozen (-30℃ to 100℃). 【Part 5】 Best-before date: 3 years, shelf life: 10 years. ⭐︎Please refrain from purchasing if you are concerned about minor details, as it is stored at home. ⭐︎As it is drinking water, we cannot accept returns or refunds. Please understand this before purchasing. ⭐︎It will be shipped in simple packaging.
