SET OF 1 - This dolphin is a super cool fidget! The sea creature is quite large measuring in at 7" long and 2" wide. The critter is made up of several hard plastic bowls that are connected. This gives the animal a jointed and robotic movement. You can twist and spin the dolphin in your hand. The hard plastic makes a nice sooting sound as the colored cups rub together and move. It is quite mesmerizing to feel. Great sensory toy. ASSORTED OEN PER PURCHASE.
