These are domestically produced shell pearl earrings, carefully crafted to express the color and luster of genuine Akoya pearls. Approximately 6.5mm. I think it's an easy-to-use size. Smaller ones are petite, elegant, and cute, but if you find them a little lacking, how about this size? In my personal opinion, they look the same color as my real pearls at a glance. They have a beautiful peacock color with green and a hint of pink. The mellow luster and unique individuality of real pearls are attractive, but these are more resistant to sweat, sebum, and scratches than real pearls, and are more durable than natural ones, making them easier to use. They have a moderate weight, just like real pearls, and look more natural than plastic or resin. They are of stable quality being a domestic product, but since they use natural shells, there may be some minor imperfections like dimples, scratches, and slight differences between the left and right, just like natural pearls. When worn, the luster makes it difficult to notice scratches or differences, but please refrain from purchasing if you are at all concerned. Surgical stainless steel. Not everyone is guaranteed to be allergy-free. Comes with silicone catch. Please hold the base gently to prevent them from coming off. There may be some adhesive overflow to increase strength. Please be careful as the photos are close-ups, so you don't end up with a size you didn't expect. Please refrain from purchasing if you are looking for a perfect product like a ready-made item or if you are particular about details. Simple packaging without a box.
