The ferocious T-rex had very, very tiny arms. It’s what made them so angry–not being able to scratch their backs + all. So what better way to become an angry, short-limbed T-Rex than by turning your fingers into tiny T-Rex arms! The stretchy rubber skin gives these dino claws a life-like look + feel. Cheapest Halloween costume ever! Each finger puppet is approximately 2.5 inches long.
