This is a heart chain necklace from the brand CREA. Color: Gold Total length: Approximately 42cm (The fourth photo is from the website) This necklace is made for those with metal allergies. It's made of stainless steel, so it's also resistant to water and sweat. I bought this myself because I have a metal allergy, and I never experienced any itching! (※This does not guarantee that everyone will not have an allergic reaction) There are no noticeable stains or scratches, but please understand that this is based on my personal assessment.
