This is a Bollina shower head. I purchased it several years ago and stored it after using it for about a week. Calcium deposits from tap water are attached to the shower head, but it can be used without any problems. An adapter is also included. Retail price is 15,180 yen. Quoted from the following site: TK-7100-P Our store is the official store operated by a group company of TKS, the manufacturer of the "Bollina" shower head series. Bollina (Bollina) Ninfa+ (Ninfa Plus) achieves beautiful skin, beautiful hair, and water saving with ultra-fine bubbles. Ultra-fine bubbles created by Bollina envelop the body with extremely small bubbles, providing an exquisite feel on the skin. It enhances the cleaning power, moisturizing power, and heat retention of the shower. Thank you for viewing.
