I have a total of two of the Airlift F30 cpap mask that I ordered by mistake and I cannot return. One of the masks I had opened before I realized my mistake that mask I just put in a ziplock bag with the original packaging. Both masks are brand new unused condition one is sealed in original package and the other is in a ziplock with the original package. I paid 55.00 originally for the two I will let the pair go for 40.00 plus shipping.
