So far I LOVE these!!! I have extremely picky ear holes, to the point that I would react even to 14k gold earrings. I don't change them out, just wear the same studs every day, and sleep in them, so I need earrings that won't cause an infection. A couple friends have been sporting these bar earrings (not the same brand, just the style) and after lusting after them, decided to hunt some down on Amazon. They're exactly what I wanted and hopefully the 24k is pure enough for my precious little sensitive ear holes.
