⚠️ Although this item is unused, the bag was removed once for photography. This is a server that generates hydrogen water called "Genki Suiso Sui" (Healthy Hydrogen Water). It generates hydrogen water by plugging it into a power outlet. I received this as a gift. I heard it costs around 50,000 yen at retail price. This unit uses tap water from your home to generate hydrogen water. Hydrogen water has an image of being expensive, but I think you can drink hydrogen water very easily and relatively inexpensively! An instruction manual is also included, which explains how to maintain and set up the unit. Please feel free to contact me if you would like to see photos from other angles.
