Thank you for viewing! We offer valuable lifestyle products at affordable prices. This is a set of earring backs. The exterior is made of silicone and the interior is made of gold-plated metal. The double-lock system of silicone and metal securely holds your earrings in place. Silicone is a material that is less likely to cause allergic reactions, so it can be used by those who are sensitive to metal or have allergies. These are easily lost, so we offer them in a set of 10! This time, we'll include one extra as a bonus, for a total of 11 pieces. 《Regarding Shipping》 ◎ Address changes are not possible after purchase. ◎ Items returned due to an incorrect address will be resent at the buyer's expense.
