This is a blue ceramic necklace. There appears to be some kind of engraving, but I couldn't read it with the naked eye. Thank you for looking. I often collected accessories from overseas and Japan. I think there are many vintage items. *Please read the profile. Regarding the size, there may be some errors due to amateur measurements. Please understand. Also, there may be oversights in the inspection. Please understand that the items are worn or used. When shipping, clothes and foldable bags will be folded. I will pack them carefully, but please understand. I am also organizing the house and will gradually sell items from my mother and grandmother. The main items are clothes, jewelry, and books. My mother loves clothes and picture books and has a lot of them at home, but her closet and rooms are getting full, and she has decided to get rid of some items she no longer wears or books she doesn't read. I will be listing them little by little. Thank you.
