High-performance water purifier cartridges, STC.V2J model, set of 2. - Model: STC.V2J - Quantity: Set of 2 - Substances removed: Mold, odor, lead I'm not sure exactly when I bought these, maybe around last year, but I've stopped using them so I'm selling them. They've been stored at home somewhat carelessly, so some of the containers are dented, but they are new and unused. Please refrain from purchasing if you are concerned about this. When shipping, I will fold the box and ship via Takkyubin Compact, so please be aware of this.
