Super realistic! Authentic detail! Recommended for all Jurassic Park fans, not just kids! You can control the T-Rex's movements with the controller in the glove. You can enjoy realistic movements with opening mouth, sniffing, roaring, blinking, and chomping sound effects. Dimensions (width x height x depth cm): 40.0 x 26.0 x 18.0 cm Assembly: Not required Batteries required: 1.5V, 3 AAA batteries (sold separately) Used a few times, but in excellent condition. Thank you.
