Review on 💎 THUNARAZ 16 Pairs 20G Stainless Steel Cartilage Stud Earrings Set for Women Men - Barbell Helix Tragus Ear Piercing with CZ Screwback - Stylish Ear Lobe Piercing Jewelry by Jan Keller

I am very sensitive to some materials and will react within seconds. I had no reaction to these earrings. It's already day 3 and they've weathered 2 showers with no back fading or weakening. They are also comfortable for sleeping. The backs were a little difficult to screw on because they are so small and difficult to get a hold of, but after a minute of wrestling they screwed on well and haven't come loose. If you don't have good manual dexterity, ask someone to help you spin. Highly recommended for sensitive skin/ears!
