My team and I have sensitive ears, too! Our goal is to provide high quality, affordable, hypoallergenic options for our sensitive-eared girlies. All materials are listed in each product's item description. We use stainless steel, surgical steel, and implant grade titanium in our earrings. These materials are rust and tarnish proof and won't turn your skin green.
If your ears are extra extra sensitive, I recommend giving our flat back earrings a try! They're made of surgical grade materials. Less than 1% of the population is allergic to true implant grade titanium, which makes it the best metal for sensitive skin.

Note that our gold titanium flat back studs do have an 18K Gold PVD plating. If you have any additional questions, please don't hesitate to reach out.
