This is a necklace and pendant top that my son, who was a university student a few years ago, used to wear. He no longer needs them, so I'm putting them up for sale. They are used items, but there are no noticeable scratches or stains. I'm not sure of the material, but the round pendant top in image 2 is magnetic. The cross in image 6 is not magnetic. The silver pendant top in image 9 is also not magnetic. The silver ring-like pendant top in image 13 seems to have been used as a necklace with a chain attached. The silver chain in image 13 is not included. Please check the images for the size and other details. The total weight of the three items is approximately 45 grams. They will be shipped via regular mail (Teikeigai-yubin).
