Please note that they are not anodized but painted. A month in the sun and they just aren't the color you bought them. If you buy them, use an anti-seize agent before putting them on. The heat from your brakes will soften and harden the paint around the valve stems. I actually had to take my bikes to a service station where they broke the tires and installed new valve stems. I just wouldn't buy them unless you have a car with a trailer that you never want to drive or on the road. Simply put, they cost $5 to buy and install and at least $100 to remove.
