-Earrings are made out of sturdy hard plastic -Earring posts are made with high quality surgical stainless steel posts -Earrings come with a super cute gift box PLEASE NOTE: Your earrings will come in a small gift box.. BUT I can only send one box per 4 pairs of earrings. If you order more than 4 you will get an additional box. I simply cannot afford to give a box for every single pair of earrings. If you would like to buy an extra box please do so and add this link to your order: https://www.etsy.com/listing/291233579/gift-box?ga_search_query=box&ref=shop_items_search_1 Example: If you order one pair of earrings you will get one box.
