Puppies in a Basket Swing Card. The most detailed, well-designed, and interesting cards we've ever seen! Not only does each card pop out easily from an envelope into amazing 3D shapes, but each also has a multiplicity of moving parts that allow the objects in the center to swing back and forth. Personalize your greeting in the provided space and mail in the included envelope. All cards measure 5-3/4" wide by 7-3/4" tall.
