Review (3/5): Careful not to lose them!  They come out really easily.
For the price, I'm not complaining. I got 40 tiny studs for less than I've paid for a single surgical steel nose stud at piercing outlets. But they are certainly not what you'll get at most piercing outlets. The stud shaft is significantly longer than it needs to be, so there is a lot of shaft length inside the nostril, which either means it can poke against the central bridge of your nose with the slightest bit of pressure, or it can stick out from your nostril - sort of like those meat thermometers in turkeys that pop out when they're done cooking. They are a very thin gauge - like 22 - and the little barbed ball on the end is really not enough to keep the stud from pulling out really easy unless you have the ultimate tiny piercing hole. Mine is definitely not big - an 18 gauge hoop wont even think about getting through mine even lubed up. I've pulled this stud out several times getting it stuck in the towel when I get out of the shower. I lost one already that way, and the other two times I found it right away in the threads of the towel. Didn't even feel it pull out - just noticed in the mirror that it was suddenly gone.
The other thing is the color choices - they aren't my favorites, but I guess they're not bad if you're into these colors. Not what I would have chosen for facial jewelry. Like peridot? Why would anyone want a tiny gemstone the color of a booger on their nostril? There's 5 each of 7 different colors in the set of 40, and 2 of the rows are clear crystal, which I like. The other colors in my set are Ruby red, dark teal, light pink, booger green, and two shades of blue, light and dark. I would have happily swapped out the green or either blue for an amythst purple, but ah well. No purple for me. Black would have been versatile and welcome too. The ruby looks like a tiny spot of blood on the face, so pretty sure I'm not going to wear that one, and the blues and booger green are out too. So out of my 40 studs, I'll probably only wear the clear and the topaz, maaaybe the teal. I hope I don't lose them too quickly.
