Purchased a few years ago and worn a few times. *Please note that the box is not included. CAREERING / PLACEBO 301F Thickness 3.5mm x Diameter 18mm The post that goes through the ear is made of 18K material, which is particularly resistant to allergies. These are hoop earrings from CAREERING. Used a few times, and there are some minor scratches due to storage. I have tried to take photos so that you can see the details, but please comment if you have any oversights or concerns. There are no accessories. This is a listing for both earrings and the catches only.
