"Love these earrings. I got the 6mm length and I think I'm going to try the 8mm next time because though they are a great length for sleeping and not getting in the way, they can be a bit harder to get off. Also, the long end is supposed to be inserted from the back and you slide the short end in at an angle at first (part of the locking in mechanism). Other of their earrings have that direction in the photos but this one didn't so just fyi! Got the 4mm size circle and 20G."
