This is a filter cartridge for the Every Frecious water purifier *ˊᵕˋ* We use the "mini" model at home, and I was keeping this as a spare, but I'm selling it because I haven't had a chance to use it. It's a new, unopened product. The outer box has some scratches and minor damage from storage, as well as traces of a shipping label being removed, so please check the photos. For those who understand that this is a home-stored item, thank you in advance ❁⃘*.゜
