Made by Nordic Offroad (Andover, MN) a company run by Ross Duvall, these are the world’s first penis-shaped valve stem caps.
Screws right on the tire valve stem.
Great for pranking. You can even buy them and sneakily put them on other random people’s tires.
Doesn’t affect tire balance.
Works on many different tires (car, truck, bike, motorcycle, etc).
