At just 10mm, these sleeper hoops are very small and therefore perfect for little ears and those that still require an earring 24/7 as they heal. Constructed from gold plated sterling silver, they have a delicate, diamond cut design and measure 1mm wide and 10mm in diameter. The hoops can be trickier to fit due to their smaller size, but a hinged, 6mm pin helps and you will be rewarded with a snug fit that's secure and comfortable enough to sleep in.
