This is a work by the popular Instagram artist, iu. These earrings have titanium posts, making them hypoallergenic. The photos of the earrings being worn (pictures 3 and 4) are of a different shape because they are the earring version. I used them once and then stored them in an accessories box. I'm selling them now because they no longer suit me. ********************************************** Immediate purchase is okay if you agree with the description.
