Color — Graystone Base with Carafe and recharge connectors. In like new condition with original packing material. Lovely item that my naturopath recommends. I just don't use it. Lives in a clean, smoke and fragrance free home. From the Mayu website: The MAYU Swirl is a science-backed hydration device, inspired by the movement of natural spring water. The vortex motion restructures water molecules and increases oxygen, enhancing cellular hydration and providing a smooth, refreshing taste. HOW IT WORKS? The whirlpool motion recaptures lost vitality by allowing oxygen to balance and alkalize your water 6,000 times faster. Each base is individually handcrafted, featuring its own distinct swirling porcelain pattern. No two are exactly alike—each one is a one-of-a-kind piece made just for you.
