After years of not wearing earrings, when I finally wanted to put some in, I found the holes had closed up. It had been so long since I had them done, I wasn't sure where to do it, so a DIY seemed in order. These were exactly what I wanted. They come in sterile packaging and even include 2 alcohol wipes, so you have everything you need. The posts are nice and sharp and the backs are very secure. I had no trouble getting them through. I've had them in almost a week now and I've had no problems. Very happy with my purchase.
