Vintage Berkander Christmas Holly and berries earrings

This is a pair of vintage clip back earrings still on a Merry Christmas retail card, unused by Berkander. Earrings are mint, card bears smudges & light edge wear as shown. These are some type of plastic. The red 'berries' are also plastic but composition looks somehow different than the green portions. Silver tone metal backings. Measures 7/8" in diameter.
