Review on Dsycar 12 Pack Tire Stem Valve Caps Black, Thin Blue Line American Flag Hexagon Shape Design, Premium Metal Aluminum Rubber Seal Tire Valve Stem Caps ,Universal Fit (Mini - Black Blue USA) by Robin Naber

I put these on, and approx 3 months later, I had a low tire. I went to put in air, and could not get the cap off again. It has rusted onto the valve stem. I checked the others as well. Same thing. All stuck on. We got three of them off at the tire store with lubricant, but had to remove tire and replace valve stem on one of them. Do not buy these. They will stick onto your valve stem and you will not be able to get them off.
