Emerald Baguette Stud - Flat Back (Single)A clean pop of rich and brilliant color on the ear, this is a daily staple you'll put on and won't take off. 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. To take them off, gently twist each half in opposite directions and pull them apart! Details: 3 x 1. 5 mm
