The Perfect One Hydrogen Server Dokodemo Fonten Cartridge Dog x 9

This is a replacement cartridge (filter) for Marukan's THE?PERFECT ONE Hydrogen Server Dokodemo Fountain (for dogs) water dispenser. This listing is for 9 boxes, with 2 cartridges per box (2 months' supply). Please note that the water dispenser itself is not included.

I am selling these because I use the same brand's hydrogen server but accidentally purchased the wrong filters.

Thank you for your consideration.
