Query: Wish I could wear

The product does exactly what it says it can do, after trying many others I love the design and appearance of this under my bras. I have very large breasts for my size and work in a very conservative formal environment;the last thing I want/need are my nipples showing under my clothes. I loved them, at first. The reason I have rated it so low is that I cannot wear the nipple covers, I wore them without complaint twice, the third time I felt itchy and had red markings around my nipples.The last time I wore them I washed them before wearing, put them on and had to take them out 15 minutes later that lasted more than 24 hours. They are great, if you have insensitive skin that does not irritate easily.
