Qinlorgo Soft Nasal Oxygen Cannula for All Brands Of Oxygen Generators - Household Universal Double Hole Soft Nasal Cannula Disposable Nasal Oxygen Tube(4m)

I found this ‘Soft Nasal Cannula’ very uncomfortable and it was not soft at all, using a cannula during sleep it’s important for it to be soft. I could not continue using it. Quite disappointed and unable to return it once tried. Monica Ward
