They are incredibly thin, it feels like I could break them in half with very little effort but that's to be expected for the price I guess. My pack was also opened and there were only 7 in it. I'm assuming the measurement markings are correct, so they'll probably work if you just need them for measuring, but they won't even make a great ruler because they're so flimsy.
