It's super hard to find legit solid gold nipple jewelry and then in walks Miss Faythe! Solid gold barbell with internal threads. You don't have to doubt if its solid and worry that its some kind of plated junk disguised as the real deal because IT IS THE REAL DEAL! I put the dang thing in and haven't taken it out since. No irritation. No soreness. It's a beautiful piece of jewelry and I'm so so glad I stumbled upon this queen on Insta and found her shop. Worth every penny! I need to get my other one re-pierced and get another one of these for sure! I did need a different length then offered and a quick email back and forth made it a breeze to get what I needed and its perfection.
