Many, many feelers in one set. The gauges sort of feel like they're made from metal scraps because they're not all from the same alloy, one of them had a blurry print on it, and they're all covered in some kind of goop, probably anti-rust, so cleaning before using is probably a good idea. The most important thing though is that there's plenty of feelers to choose from and they're really, really cheap, so you can have the setup essentials without breaking a bank. Nice.
