This is a bless necklace. It was included in a lucky bag. I don't know the product details. The material is stainless steel 316L, so it can be worn in the bath or sea without any problems. The chain length is 46 cm. It has an adjuster, so it can be worn 5 cm shorter. The color is pink gold, although it may be a little difficult to see in the photos. If you have any other questions, please feel free to comment. Material: Stainless steel
