Thank you for viewing my item (*^-^*) I've made some summery whale shark earrings. The metal parts are stainless steel. Stainless steel is a metal that is less likely to cause allergies, but it doesn't guarantee that allergies won't occur. These are handmade, so they don't have the strength or perfection of mass-produced items. I look forward to purchases from those who understand this. Instant purchase OK
