Review on Mavota 4 PCS Style Polished Aluminum Chrome Tire Valve Stem Caps (Green) by Hunter Siemon

I'm not sure if it was brass on my valve stems or "aluminum" on those stem caps but they were so badly corroded I couldn't could help but remove them from my tires to add air. I had to use a cutting tool and cut them off the valve stems. I drive my truck a lot in the winter, so I know it gets a lot of salt off the road, but I still didn't expect brass or aluminum to behave like this. Otherwise they looked great! If I buy them again I will make sure to put some lube on the valve stem before installing them on my truck.
