INCLUDES 1 RANDOM COLOR - These dragons are a super cool fidget!   The critters are made up of 3D printed plastic parts that are connected together.  This gives the animal a jointed and robotic movement.  You can twist and spin them in your hand.  The hard plastic makes a nice sooting sound as the pieces rub together and move.  It is quite mesmerizing to feel.  Great sensory toy.  These are 8" long, and the matching screw together egg is 3.5" x 1.25".  These come in 3 cool chameleon colors.
