Great carbon fiber keychain. Well made with some weight and doesn't feel cheap at all. The valve stems look cool too, but I didn't bother with their length (slightly longer than standard sized valves) and the fact that they're really smooth and completely round (hard to get to if/when you need to remove them. I I ended up buying another set of valve stems with folded edges for better grip, but the cost was still high, and I put valve stems on my kids' bikes.
