Steve 3 Well they are pipe bits. Good for protection of your pipe stem. There are other reviews here that say they are “thick” ……that’s the point, they are a rubber bite guard against teeth chatter marks on your nice pipe stem. They are just right with mouth feel and sit nicely on your teeth. BUT AS EVERYTHING here on JP Amazon. There is a huge price gauging going on. I’m actually surprised that Amazon allows this as the over pricing is so terrible you have to literally shop around both in the site as well as others just to find a competitive price.
