Dog water modifier catalyst, size: big. - Brand: BeeMeeNee - Model Name: Water Modifier Catalyst big - Included Items: Instruction manual, sticker - Intended Use: For dogs - Size: big Thank you for viewing. The box's plastic wrap has been opened, and there is some dirt on the box, but the contents are unused. I purchased this around March 2025, but I didn't use it, so I am offering it for sale.
