Hakusui Ivory Co Ltd daisy screw on earrings. Stock #1284. I found these in my mom's (born 1984) house after she passed earlier this year. Unfortunately I know nothing about them other than they were found in a jewelry box that quite possibly had been my grandmother's. The box is in ok condition, but the earrings look as if they've never been worn.
