This is an adjustable chain necklace, but the clasp has come off and I've lost it. You can find clasps at 100-yen shops, but I'm not very good with my hands, so I'll offer it as is at a bargain price. You could also take it apart and use the parts for handmade crafts. It has four types of natural stones: Lapis Lazuli… A versatile stone for happiness and good fortune Tiger's Eye… For boosting financial luck Smoky Quartz… To ward off ill intentions from others Morion… The strongest stone for protection against evil and bad luck Main body: Approximately 15 cm Chain: Approximately 5 cm - Colors: Black, Blue, Brown - Materials: Metal and natural stones - Clasp: Chain type - Size adjustment: Adjustable Thank you for looking.
