Bollina Tanaka Metal Shower Head Ultra-Fine Bubble Used for several years No malfunctions Includes 3 unopened attachments Handle width: 30mm Water flow rate: Approximately 8.94L per minute Water saving rate: Approximately 18.7% Body weight: 140g The Bollina shower head from water faucet manufacturer Tanaka Metal. Generates micro-nano bubbles from water pressure using the patented μ-jet technology. These ultra-fine bubbles reach deep into pores, improving warmth, moisture retention, and cleaning power! Cleaning with a citric acid soak should make it clean. It's an ultra-fine bubble shower head that saves water, but the water pressure is surprisingly good for water saving, which I liked. I also used this product to fill the bathtub with hot water. The feel on the skin is different from regular hot water. It also cleans dirt from the scalp well. The usability was good. I am selling it because I have switched to a different product. The Ballina shower head is made of metal with a chrome finish, featuring a stylish design. - Model Name: Ballina - Material: Metal - Design: Chrome finish - Function: Shower Head Thank you for viewing. - Material: Chrome-plated finish - Design: Curved handle with textured grip - Connection type: Standard shower hose connection Thank you for viewing.
