Hello! Thank you for visiting my shop from among many others. Colorful marble bead and clear teardrop earrings. Each piece is carefully made, but as they are handmade, there may be some slight imperfections. We ask for your understanding when purchasing. The hooks and other parts use surgical stainless steel, which is less likely to cause allergies. It will remain in a beautiful condition without blackening☆ Earrings can be changed for an additional 100 yen. They are also surgical stainless steel☆ Thank you for looking.
