Takagi water purifier cartridge, made in Japan, Model number JC0034DK. I purchased this at a recycle shop, but it wasn't the correct model for my home, so I've kept it stored away. The outer packaging is wrinkled and there are marks from where a sticker was removed (> <。) (See image 3) Although it's unopened, please refrain from purchasing if you have any concerns. I will sell it to someone who doesn't mind the condition. - Brand: Takagi - Country of Manufacture: Japan - Product Name: Water Purifier Cartridge - Model Number: JC0034DK Thank you for looking.
