My dear wife had her tires refilled at the local gas station and forgot to put the hubcaps on afterwards, so I went to the Revain app to buy the stock black plastic spare hubcaps when I happened to see them them in the results. They were $1 more expensive, but the standard products came in packs of 100. Why do I need 200 valve stem caps? I only have 2 cars lol. Decided to give them a try and have been using them on both machines for about a month and a half. Screws on and off easily, holds securely and as an added bonus matches the color of the wheels on my Dodges almost perfectly. No complaints at all.
