I had a breast reduction a number of years ago and one of the side-effects is that my nipples are always on "alert". (Kind of embarrassing.) I found these concealers and use them whenever I'm concerned and they do a great job. They are fairly invisible under your clothing. I have to take them off after 6-7 hours, though, because they start feeling itchy. I'm glad I bought them and they are so well made that they will last for a long, long time.
