VOLUKAPack of Titanium Screw Back Surgical Stainless Steel Earrings Geometry Hypoallergenic for Sensitive Ears Studs for Women Men Cubic Zirconia Back Piercing Post 20G Helix Multipack Feather Moon Heart Round, Cubic Zirconia, Cubic Zirconia

I got these for my daughter, but she gave me a couple of the pairs. The assortment of styles are cute. The backs screw on, which can take some practice, but they don't come loose and are super comfortable to sleep in. As a side sleeper, regular earring backs can be poky and annoying, but I don't have that issue with these.

I've got other flat-back earrings and the backs are kind of hard to grab on to. I really like that these are little larger and have an area with grooves cut in to provide extra grip to unscrew them. I like that the backs have a little jewel on them - it adds a fun surprise when you see the backs of my ears.
