Vintage Set of 4 Hallmark Holly Berry Napkin Rings

This is a vintage set of 4 Holiday Napkin Rings from Hallmark It features a pretty border of green holly leaves and red holly berries. They measure 1 1/8 inches wide and 1.5 inches in diameter. They appear to be made of plastic, and are still in the original box. I think these were released sometime in the 70's or 80's. The napkin rings are in perfect condition, but the box is a bit scuffed.
