Advent calendars heighten anticipation as children and adults celebrate Advent and prepare for Christmas. They create fond memories for loved ones to cherish through the years. Our Greeting Card version is an easy and thoughtful way to send a gift in the mail and let the recipient know you are thinking of them. Measuring about 4.75 x 6.75 inches, this card may be sent by regular postal service and is the ideal size to keep out throughout Advent. Let someone know you are thinking of them by sending them a card which they “open” 24 times.
