One point accessory that can be attached to the rubber air valve on the wheels. This is a dress-up item that covers the rubber part of the rubber air valve. Easy to install. Simply remove the air valve cap and place it on the rubber part with silver, red, blue, black, gold, and titanium tone aluminum anodized treatment, so you can coordinate it up to the base of the rubber air valve. Use it with a pair of air valve caps for more effective results. Please be aware that the posted image is a sample, actual shape, color, and component components may vary.
