I wanted to wait until I actively use them for review. I was nervous about buying them but needed new caps. Since there weren't many of them (for the price) other than the simple plastic parts that needed to be replaced regularly, I decided to give it a try. The soft plastic set will begin to deteriorate over time under the effects of the weather. However, they appear to be metal and have beautiful rhinestones around the lid. After a few months of use they are still shiny, showing no signs of wear and EVER! This is what I was looking for and boy am I impressed. These kids still look good after thousands of miles!
