Brand new, unopened product. This is an overseas product. 2-piece set of nasal dilators for sports, similar to noson, which improves breathing and sleep. I bought these for myself, and since I had a set of two, I'm selling the extra one. I have a sensitive nose, and when I put it on, I feel so happy that I can breathe naturally through my nose. The news said it was more than double the effect, but I feel it even more than that. Also, after wearing it, I didn't even notice it was there, and I had to check to make sure I was still wearing it. This is just my personal opinion. Please check my profile.
