This delightful card doubles as an adorable doggy display! Our circular Doghouse Party Pop-Up Card folds flat at 6½"x5½" for mailing in the included envelope, and recipients will get a precious surprise when they unfold the missive and slide the tab along the card's surface until it locks into place: a playful scene filled with canines that wiggle and wag their tales. Pup lovers will cherish this 3D card for a lifetime—especially with your note on the bottom.
