This is a set of a pet automatic water dispenser, Pure Crystal, including two packs of drink bowl softening cartridges (2 per pack) and one softening filter (full circle type). The softening cartridges are new and unopened. The softening filter is one out of a pack of 4, also new and unopened. I'm selling these because I replaced the water dispenser. #cat #PureCrystal #softeningcartridge #softeningfilter #fullcircletype
