Takagi water purifier replacement cartridges. - Brand: Takagi - Product Name: Water Purifier Replacement Cartridge - Model Number: JC0032UG 4 pieces - Model Number: JC0031 1 piece I am selling these because I can no longer use them after replacing my faucet. They have been stored at home, so there are wrinkles and scratches on the bags. They have not been opened, and none of the bags are torn. Please research the compatible faucets yourself. Thank you. I can sell them individually, so please comment if you are interested.
