Earrings jackets hard plastic pink aqua clear set of 3 Avon ?

This listing is for three sets of earrings jackets. They are made of a hard plastic and are in three colors: aqua, pink and clear. They are used with stud earrings (studs not included). The jackets are about 1 inch in size and in great shape. I believe these are older Avon but they are not marked.
