Great Customer Service
I ordered two of these studs to wear as flat back earrings. If you do research on them (or nap earrings they are sometimes called) the industry standard was/is 6mm, so that’s what I ordered. Maybe I have thin ears?!? Lol. But way too long. This was a non returnable item but they allowed me to exchange for 5mm instead. They were lovely to work with and I love my studs.
