The product is a complete set of McDonald's Kirwin Frost McNugget Buddies from the year 2023. This set likely includes toys or other collectible items that were offered as part of a promotion with McDonald's food, particularly with purchases of McNuggets. The open box suggests that the items have already been removed from their original packaging, but the paper would indicate that the promotional materials were still included in the set. It would be a nostalgic or fun item for collectors or fans of fast food toys.
