A major hit product with cumulative sales exceeding 130,000 units. Made in Japan. Engineers conducted extensive research and arrived at a bubble size of 20μm, which demonstrates the greatest cleaning power against sebum and other dirt. The adoption of the unique "special ejector method" technology of Aura Tech, a micro-nano bubble specialist company, has made it possible to generate a large and stable amount of 20μm microbubbles. Economical with water-saving effects: The special nozzle used in the showerhead provides approximately 40% water-saving efficiency (according to Mizuki Science and Biology Co., Ltd.). Thanks to our unique technology, you won't feel the lack of water pressure that is often associated with water-saving microbubble showerheads. Gentle bathing effect: The hot water generated by the showerhead, which produces microbubbles, has been confirmed to increase blood flow in human skin and warm the body, similar to the effects of a hot spring (excerpt from the latest technology of microbubbles and nanobubbles). Furthermore, results show that it is less likely to cause you to feel cold after bathing. Excellent cleaning effect: Due to the microbubbles' ability to adhere to dirt, sufficient cleaning power can be obtained with the Purebble II showerhead even when reducing the amount of soap and shampoo. It gently cleanses delicate skin without removing excessive sebum. Moisturizing effect: It has been confirmed that the skin moisture immediately after showering with Purebble II is about 15% higher than when using a general showerhead, due to the effects of microbubbles. An adapter for KVK is included for connection with the hose. This is a used item, so there may be minor scratches and dirt. There are no issues with use.
