A MILK necklace from the Showa era. I have kept it at home. I think the material is silver. (I don't know because there is no marking on the item) Only the robot's hand spins around. The width (diameter) of the ring is about 1 cm. The length of the chain is about 70 cm. The head is removable. Because it is a necklace with length and weight, I listed it in the men's category, but I think it can be used unisex, regardless of gender. The screw on the right shoulder seems to be slightly misaligned, but I don't think it will be a problem for use. (Photo 2) There are no noticeable scratches, but it is an old item. I used to love it about 35 years ago. Therefore, I have marked it as having scratches and dirt. For those who understand that it is a used item and has been stored at home, thank you very much.
