Thank you for viewing my items. I found this while decluttering. Unfortunately, I'm using a different water purifier, so I no longer need this. It's a waste to just throw it away since it's still usable, so I'm putting it up for sale. Torayvino Kasetto Series Compact size Although it doesn't have a box, it's an unopened cartridge. It's a new, unused item. The outer bag is not in good condition, and I'm not sure when the printing on the cartridge was done, so please check before purchasing. MKC for Torayvino Kasetto series. Compact size Water purifier replacement cartridge - Lot No: K2Z16 - Quantity: 1 (No box, no instruction manual) - Color: White Please understand that this has been stored at home before purchasing.
