This is a special limited edition model with a list price of 460,000 yen (including tax). ※ The regular version has a list price of 290,000 yen (including tax). I believe this product is rarely available now. I received this as a gift. I was told it's unused. Both the main unit and accessories are unopened. The instruction manual shows some minor soiling. I am offering it for sale at a 60% discount off the list price. Create your own rotating energy water! By passing water through the Hexagon Conversion Device, it provides safe water that is resistant to bacteria. Water that has passed through the Hexagon Converter increases dissolved hydrogen. It also activates lactic acid bacteria. Because it is difficult for bacteria to multiply, it is useful for deodorization and maintaining the freshness of food. By allowing water to come into contact with π ceramic, π (Pi) water is created. Pi water is said to be water that is similar to the water in the human body.
