I've had 4 of these and this is the second time in a few years that I've forgotten to check a tire after a repair. This place fixed my tires for free, so I know they're the most common place for valve caps to be thrown on cars after work. I decided to buy 4 packs instead of asking this place to give me some new caps. These valve caps are exactly the same as the 3 I have left over so it all worked out great. They look stylish and hold up well. Just remember, when the tire changers fix your car, tell them to remember to put those caps back on. Or remove them before picking up the car. :)
