The first thing that gave me a red flag on this item was that the directions and warnings were not translated correctly. Actually, it was so bad I could see a possible law suit, but will leave that alone.Second, the packaging had more of a feel of something you would get at a "porn" shop and not something actually packaged for women.Third, they were wrapped in a plastic covering which was almost impossible to get off.And last, I am a 36D and like to wear thin, cotton bras and even though I have small nipples I always seem to have "my headlights on". So I really wanted something so I would not always be giving a "free show". The petals did attach and stick properly, but even through my bra if I "got cold" I could still see the high beams. I am happy I didn't spend much on these. Very unhappy with them. My friend told me to try the ones they sell at Victoria's Secret, which I will.Would give zero stars if I could.
