Thank you for viewing! (*^^*) The hook earrings are made of surgical stainless steel. * This material is rust-resistant and less likely to cause metal allergies, but individual reactions vary. Please discontinue use if it does not agree with your skin. This is a handmade product. Each piece is carefully made, but it is not perfect like a mass-produced item... I would be happy if you could understand the handmade feel (*^^*) * We are not responsible for any skin or other problems. * Please note that we cannot answer questions regarding allergies. * Glass nuggets may break upon strong impact, so please handle them with care. * Fine air bubbles or dust may be mixed into resin works. The thickness of the earrings may slightly differ between the left and right sides. There may be differences between the left and right sides, individual differences, and color unevenness. The resin may yellow over time, so please store it in a place away from direct sunlight. * If you have any concerns, or if you are a perfectionist, please refrain from purchasing. * The color may appear different from the actual product due to lighting. Also, the color of the product may slightly differ from the image depending on the environment of your computer or smartphone. * We do not accept cancellations, returns, refunds, or exchanges. I am a beginner on Mercari (but I have experience with other flea markets and auctions), and I hope we can have a pleasant transaction. I strive for speed and politeness. Thank you (*^^*) Shape of earrings... Hook/Chain
