All our earrings are designed to be used for healed piercings.
Professional piercers use their own initial earrings and do not pierce with earrings that you bring in. This is because the UK law requires the piercer to use certain standards of materials, and if you bring in your own earrings they can't make sure that these standards are met (hence won't take the risk). We would always recommend going to a piercing specialist that will keep to the standards. Although it is a pain waiting for the piercing to heal, we would recommend to wait until the piercing is fully healed before changing the earring.
