The best I've tried yet. These discs are not sticky but do form a sort of adhesion to the skin once it's been in place for a while and has acclimated to your body temperature. I found when removing them, I had to remove it like any silicone product by carefully removing it from my skin. I like that it has a very thin profile but still guards against obvious protrusion through my bra. I typically forget I'm wearing these at all. I purchased the Braza Silicone Re-use Petal Nipple Covers, Beige, 2 Count at the same time and couldn't not get it to lay flat. It also started to thread and shred almost right out of the package. These Bezi discs are my ultimate favorite!
