If you have ever purchased a ResMed P10 CPAP mask you will notice that you get 3 nasal pillows with the mask, a Large, Medium, and Small. If you are like me you only need one size which leaves you with 2 brand new nasal pillows that are useless. Also the nasal pillows themselves wear out much faster than the mask itself. You can purchase just the nasal pillows alone for $30 each plus tax, but I am wondering if there is anyone out there willing to trade sizes if they don't use them. I have several brand new medium and small ones that I am willing to trade for the large sized ones.
