“These flat back studs are very cute, and the flat back is definitely more comfortable than traditional earring backs. I've been wearing these earings for about two weeks now and so far I have had no issues (shower, gym, sleep). They haven't fallen out and they don't bother me. I will say that they are smaller than I expected. When I ordred them, the product descrption did not give dimentions for the star, and its hard to tell from the photos how big they are - the stars are very tiny!! Shipping was very fast, they shipped within half an hour of my order and arrived very quickly. Overall, I am happy with my purchase!”
