Thank you for viewing! This is a handmade item by an amateur. It is not a mass-produced product. It is not very strong, so please handle it gently. There may be asymmetry, distortions, and air bubbles. Since inexpensive parts are used, discoloration and oxidation due to sweat and sebum are likely to occur. Free replacement. If you want a different type of hook other than a metal hook, please let me know in the comments. Regarding metal allergies: The metal fittings used are ready-made (plated). They are not allergy-friendly, so please be careful if you have sensitive skin. About shipping: It will be sent in simple packaging and delivered to your mailbox. We cannot be held responsible for any damage or loss during shipping, so please understand. Color: Pink系 (Pink-based) Discounts and returns are not accepted. Thank you.
