These ones usually are mostly brand new but we are not checking and sorting out any dirty/used right now so can list and ship fast.
All include connector + valve + membrane. None are cracked.
These ones can be either brand new, used, have water spots (manufacturing sterilizer / used washing / came from rained on boxes), have manufacturer cosmetic flaws (black spec or tiny bubbles inside the plastic), or plastic is "cloudy".
This is for ONE PersonalFit Connector + Yellow Valve + White Membrane
