This unique assortment of Z Cardz include Panthetron, Dinobot, Wolfborg, Robotion, Scowl, Rhinotank and Megahawk Earth Defenders. Z Cardz are plastic cards 6.5 inches long and 4.75 inches wide with punch-out pieces that build three-dimensional models. They come in a peggable picture box with 2 Z Cardz of a similar type with over 50 pieces. The cards are flat plastic, and you punch out the pieces and fit them together to create 3D models. The models fit together snuggly and stay together. You do not have to glue the pieces. You can take the model apart if you want to and put it back together easily. We have built and rebuilt a single Z Card dozens of times and the pieces never get loose. Many of these Z cards do have realistic movement. Each piece varies in size but each piece is approximately 5 inches by 3 inches. Retail value $6.95. Each individual box is UPC coded.
