Cool Vintage Item

These fuzzy heads are cool. I have no idea what they are called but they are cool. My mother bought them from a store for her 45 records in the late sixties or early seventies. I came across them today and she doesn't remember what they were called. Google has turned up nothing. They have no identifying labels. They do have a base that they fit securely on when not stuffed with too many records as the ones in the picture are.
