Thank you for viewing. This is a TORAY RS53 model shower head with a switch between filtered and unfiltered water. I purchased it six months ago, but the water pressure didn't suit me, so I hardly used it and have stored it at home since then. Overall, it's in clean condition with little sign of use, but there is a linear mark, about 1cm long, that looks like a scratch or stain near the connection part of the shower head (see photo 4). The included adapter is missing. This product can be installed directly on many manufacturers' shower hoses, but a separately sold adapter may be required depending on your home's shower hose. The main unit will be sent with a cartridge (RSC51) built-in. It's in good condition, but please replace it if you are concerned. - Brand: TORAY - Model: RS53 - Design: Circular shower head - Features: Filtered/Unfiltered water switch Thank you for viewing.
