These blue, mustard yellow, and black geometric stud earrings are beautiful and tasteful. They are made from polymer clay and topped with a glossy resin. Post are made from nickel-free, medical grade titanium (hypoallergenic and perfect for sensitive ears). Each stud comes with stainless steel butterfly backs for a comfortable fit. 
 
Studs measure 12mm in diameter (almost 1/2 an inch).
