Four brand new, unused, MEDIUM ResMed Nasal Pillows. All four for one price. When one gets the whole headpiece they send all three sizes of nasal pillows (S,M,L). I use large and have NEVER used these for a second. They have been stored in their box pictured in a nice clean, climate controlled area of our home. They are brand new and genuine ResMED for the AirFit P10 system.

Does NOT include the headgear, only the Nasal Pillows.

If you have questions, please send them.
