Definitely worth buying. I'm surprised I haven't had to replace one yet. I've had mine for 6 months now and the original 4 from this pack are still on me and shine bright like a diamond!
Pros
Package Includes: There are 12pcs valve dust caps in one pack, enough for your daily use and replacement, you can also share them with your friends or family members who have cars, surprise or shock them with something beautiful.
