No, we can only pierce with our earrings since they come prepackaged and sterilized for piercing, and we cannot guarantee the purity of the metal of outside earrings.
We cannot re-pierce with the old earring for re-piercing since we are a disposable studio, so you would need to get a new one. We are a disposable studio, and the earrings come in prepackaged disposable cartridges, which are used to pierce and thrown out after use. The old earring is no longer sterile, so re-pierce with it could cause an infection.
We do have two options for re-piercing: we can either re-pierce with a single matching earring of the one she already has, or we can re-pierce with a new earring and swap out the second earring to match.
