The listing, Oxygen supplies has ended.
I am no longer on oxygen and I cannot return these items. The first item is an inline humidifier, which is new in the bag. It uses standard tubing and is made for a home oxygen generator. The other items are special tubing (cannula) which is made not to hurt your ears. They are different sized and have a special padded ear wrap, so you will not get rubbed raw. All are new, unused in the package never opened.
