【Made in Japan】Bollina Wide Pearl is a limited-edition color of the most standard type in the Bollina series. It is a WC original product that combines a luxurious pearl white with a sharp gunmetal color. *The performance of ultra-fine bubbles is the same as the standard Bollina Wide. 【Pioneer of Ultra-Fine Bubbles】Bollina has a proven track record as a pioneer, selling for over 10 years. It has been introduced and featured in hotels, magazines, and on television, with over 1 million units sold in the series. The Bollina series uses the patented μ-jet technology (patented in three countries: Japan, China, and South Korea) to generate bubbles of 1/10,000 mm. Evidence of the various effects of ultra-fine bubbles has been obtained through testing by third-party organizations, not by our own company. 【50% Water Saving】Saves approximately 20,000 yen per year on water bills. Compared to a typical showerhead, it uses only half the water. Furthermore, if the amount of hot water used is reduced, the amount of gas used to heat the water is also halved, saving on water and heating costs. 【Installation Method】・Manufacturers that can be installed without an adapter: TOTO, LIXIL/INAX, SAN-EI, KAKUDA 【Please check before purchasing】Ultra-fine bubbles are invisible, so they will not make the bathtub appear cloudy when added. In environments with low water pressure, the water flow may weaken, or the minimum flow rate required to ignite the water heater may not be met, causing the hot water temperature to become unstable. *Recommended pressure: 0.15MPa or higher. *As a guide, fill a 2-liter plastic bottle with hot water from your bathroom faucet and if it fills in about 10 seconds, you have sufficient water pressure.
