TORAY Torayvino Super Series High Removal Replacement Cartridge, Pack of 2, 1 remaining. Part Number: STC.V2J I used one, but I'm selling the other because I changed the water purifier. The box has been opened, but the inner bag is unopened. Although it is unused, it has been stored at home with the outer box opened, so please consider purchasing if you understand this. If you have any questions, please feel free to ask.
