Unlike other 3D model kits, these durable, eco-friendly cardboard models are put together from one side to the other. Instead of putting the model together from the ground up, each piece is a single "vertical plane" of the object; the first piece you start with may be the center of a T-Rex, which is just a flat piece of curved cardboard. The next piece, which is slightly smaller, is glued on beside the first piece and represents another vertical "piece" of the T-Rex.
Each following piece on either side adds more depth to the figure until you have a completed, realistic-looking cardboard model! Kits come with detailed instructions and educational booklets which tell you a little bit about the animal. All kits are made with rice-based inks and 100% recycled cardboard. Finished models are approx 3"x3"x3"
