Handmade by Hollow-Point Gear, these tire caps are designed with an actual bullet casing and a sturdy screw cap inlay. The casings hold up well in all conditions and protect your valve stems from dirt, rocks, and whatever other abuse you put your vehicle through. Perfect for motorcycles, cars, and bicycles. Please Note: these bullet casings have been fired from a firearm, and as such, the casings may have small dings and aesthetic imperfections.
