"Counting down the days until the excitement of Christmas has never been so much fun, or this magical! Each day, open one of the numbered doors of the Unicorn Magic Advent Calendar to reveal a new Mini Whinnies surprise. Hidden behind the doors are a total of 15 colorful Mini Whinnies unicorns, many exciting accessories, and even a special animal friend." www.breyerhorses.com.
This model is very similar to the Mini-Sunchaser #712318 released in the Fairytale Friends Club 2020-2022. The glitter looks a little different, but these might also be overstock models.
