MJust 18 Pairs Women‘s Hypoallergenic Flat Back Stud Earrings, 20g Stainless Steel Earrings Sets for Men, Tiny Unisex Screw Back Cartilage Earrings.

These have little backs for the earrings that are flat and screw on. The smallness can make it hard to handle, but they are worth it because these are the only earrings that I've tried so far that haven't irritated my ears. I think the size and design allows more air flow and my ears appreciate it.

They are a bit smaller than I would like but very cute and they stay in wonderfully and don't poke. Can sleep in them great which is what I was looking for

Well you get a lot for the money. They are decent quality and don't hurt my sensitive ears. The posts are definitely too long though.

I have been looking for a nice set for awhile, I've tried a lot of different styles, and this set is by far my favorite. I've not used flatback earrings before and for a first time user they are super easy and really really comfortable. I have an earful of piercings and I can lay in any position and be comfortable. I wear them in the shower, they stay in all the time, and so far have not tarnished (but I'm careful to dry them after every shower, and I clean them with q tips since I'm already usually cleaning my ears anyway). I definitely recommend, it's the best value too as far as how many pairs you get for the price. They're pretty dainty and still feminine so you can wear a lot together and have that look in a somewhat understated way. Very high quality, I love them. They look good.

So cute, but turned green after several days’ wear. The green wipes off the smooth spots, but stays in the textured areas. Cute, but cheap (but also, super inexpensive so I can’t really be that disappointed, can I?)

Bought for wife. Has been wearing for months with no tarnishing. Easy on and off.

I haven't experienced any ear irritation with these. I'm able to sleep and shower with them on. Love the size so I'm able to wear multiple pairs at one time. The backs haven't screwed off on their own and they seem pretty sturdy. They also include two extra backs in case you lose one.

amazing. i love these. i can’t never find black flat back studs and i love these. hard to put in if you have poor fine motor skills. the backs are super small and easy to drop/lose. great price for quality and amount. they look cute on too.
