The stud that goes through the pierced hole is removeable, so you can use your own stud. The stud can be put through any link in the chain so you can change the length of the dangle! Whether worn at the top of the ear or the bottom, whether singly or as part of a set, whether alone or with earrings, this is a great way to get a non-pierced, pierced look. All Ear Wraps and Ear Cuffs are priced as singles. However, you can wear a pair if you choose... they're your ears!
