The thing to remember about ear cuffs and ear wraps is that sometimes they are made from wire, not just flat metal strips. If this wire has not been flattened down and rounded edges placed on them in the area that is around the inside of the ear, it becomes very difficult to wear for long periods of time.
The second thing to look for is buying the correct side ear wrap. With many ear cuffs, this is not a difficulty as they do not need to be placed on a specific ear. With ear cuffs, the entire design of the piece necessitates putting it on the correct ear lobe.
For those of you who want to get just one ear wrap or if you are like me and need symmetry and want to get wraps for both sides, I highly recommend Auntie's Treasures. Having purchased from them in the past, I know that they do use a very good inner ear wrap that is very comfortable. They have a great selection and are easy to do business with.
A classic style, if you are looking for something simple to wear, would be the Faceted Round Black Onyx Bead Short Wave Ear Cuff Wrap. It comes individually or paired.
