After wearing the 'clear' silicone plugs for well over two years, they started to get... well, not clear. Flesh colored, yes. Well knowing they are really comfortable, and easily a 24 hour wear item I decided to get a new color and change it up a bit. The 5/8" is same as the clear, and they popped right in. I purposely made sure I was buying from the same seller as they have always done very well by me. These are great and I have no doubt they will serve me as well as all the other items I have bought from them. Great buy. If you are on the fence about silicone, just do it. They are so comfortable. I don't worry about them popping out when I remove my shirts, or when I am donning/doffing my full face motorcycle helmets.
