Review on 🏴 Black Skull Style Copper Core Truck Motorcycle Bike Car Tires Valve Stem Caps - Antirust, Durable, 4Pcs/Box by Phil Prater

Looks cool but is a nuisance. I had to use pliers to get them out of the tires. They eventually broke the last time I needed air, leaving the metal caps. I basically have to knock them off the valve stems. Luckily the stems are completely intact. I went back to regular caps.
