Send sweet holiday greetings—and a fun activity, too!—to your nearest and dearest with these pop-up Advent cards! Our set includes four blank-inside 6½"x4½" cards, featuring nostalgic, glitter-dusted winter scenes that fold out into 3D displays. On the back panel of each card, twenty-four tiny doors open to reveal an image of a festive little trinket or toy. Bright red, gold-foil-embellished envelopes included.
