2 mm Emerald Dot Stud - Flat Back (Single)Our Emerald Dot Studs are super vibrant on a small eye catching scale. Layer them up, two or three in a row, to create a colorful assortment on the ear, or wear alone to catch a sparkle of lucky green every now and then. How to wear: Insert the flat back tube into the back of your ear and fasten it in place with the stud itself. Give it a little push to make sure it's properly closed, the slight bend in the post will create tension to keep it secure.
