Prepare for Christmas by opening a window each day during Advent. Upon opening each window, find a wonderful piece of gourmet milk chocolate. Also find bible text that tells a part of the Nativity story. Each Advent calendar contains 2. 6 ounces of chocolate and measures 10" x 13-3/4". Chocolate Advent calendars may contain traces of peanuts, other nuts, gluten, egg and cereals.
