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. While smaller sizes, like baby pearls, are petite, elegant, and cute, if you find them a bit lacking, how about this size? In my personal opinion, they look the same color as my real pearls at a glance. When mixed with my Akoya pearls, you might even think, "Huh?" They are that similar to real Akoya pearls. They have a beautiful, slightly pinkish-gray color. The mellow luster and unique individuality of genuine pearls are attractive, but these are more resistant to sweat, sebum, and scratches than real pearls. They are also more durable than natural pearls, making them easier to use. They have a moderate weight, just like real pearls, and look more natural compared to plastic or resin. While they are of stable quality being a domestic product, they use natural shells, so there may be some minor imperfections like dimples, scratches, or slight differences between the two, 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 catches. Please hold the base gently when using to prevent them from coming off. There may be some adhesive overflow to increase strength. The photos are close-ups, so please be careful not to be surprised by the size. Please refrain from purchasing if you are looking for a perfect, mass-produced item or if you are very particular about details. They come in simple packaging without a box.
