This 10mm single hoop earring is one of the smallest hoop that we stock. Perfect for children and new piercings, the sleeper fastener can be tricky to fit on a hoop of this size so this one has a hinge to help with this. It is well worth the effort though as once in it can be worn day and night comfortably with no worry about it coming loose. This particular hoop is made from 1mm diameter sterling silver tubing which ensures that the earring is super lightweight.
