Set of 3 filters compatible with cat water fountains. New, unused, and unopened. I no longer need these as I replaced my water fountain, so I'm offering them to someone who needs them! - Brand: Plus Aqua - Product Name: Cat Water Fountain Filter - Material: ABS Resin - Quantity: 3 filters The outer box has some scratches. Although these are unused, they have been handled by a person once and stored at home, so please understand this before purchasing. Please refrain from purchasing if you are looking for a perfect product or are overly concerned about minor details. Thank you.
