Thank you for viewing. This is a LIXIL touchless faucet, Navish. I used it for about a year and a half. Model number: SF-NAB464SYX It has a water purification function, but the water purifier cartridge and the disposable packing for the piping are not included. (Please prepare these yourself.) Although it has been cleaned, please understand that it is a used item before purchasing. Immediate purchase is OK. Even if there are comments, the person who purchases first will be given priority. Thank you for your understanding.
