Review title is Uncomfortable, didn't work on most of my earrings [SEP] I really think the company put more enthusiastic design into the almost bombproof packaging of these earring backs, than the backs themselves. They are decently done and look nice. But in using them, I was not verypleased. Several pairs of earrings had posts that did not fit through the hole in the back; it is too small. It didn't seem to help with some others. I had one pair of earrings that seemed to benefit from them, but they seemed so bulky that It was uncomfortable. I have small earlobes and they sit close to my head. If you have large earlobes, or your problem is that your holes are stretched out, they might be helpful for you.
