Thank you for viewing. This is a SANEI (San-ei)浄水 shower head. * Brand: SANEI / San-ei * Product: 浄水 Shower Head (Water Purifying Shower Head) * Features: Water purifying shower that cuts residual chlorine It doesn't fit my home shower hose, so I'm offering it to someone who can use it. I only ran water through it once. I will also include a spare cartridge. I have lost the included adapter. The opened cartridge has been used once to test and water has been run through it. The main body will be wiped with a disinfectant wipe and then wrapped in bubble wrap before shipping. (※ No box or instruction manual) If you are concerned about minor details, please refrain from purchasing. Thank you.
