These earrings are made of skin-friendly surgical stainless steel. Surgical stainless steel is the same material used in scalpels and scissors for surgical procedures, so there is no worry of discoloration, rust, or metal allergies. The parts used are SUS316L (a high-grade surgical stainless steel). White shell pearls in different sizes (6mm and 4mm), suitable for formal occasions, are connected to add a touch of design to the simple look. Motif length (excluding earring parts): Approximately 15mm ・Shell Pearl Artificial pearls made by coating a pearl foil on a core made from shells used for cultured pearls. Shell pearls are artificial pearls that pursue authenticity, so their weight is almost the same as real pearls. I think it's the hardest to distinguish from real pearls. The biggest feature of shell pearls is their "ease of handling." Compared to real pearls, they are resistant to sweat and dirt, and have excellent durability, making them suitable for everyday accessories. Base material...
