INCLUDES 1 RANDOM COLORS – These slugs are a super cool fidget! The bug is quite small and cute measuring in at 4.25″ long and 1.5″ wide. The slug is made up of several hard plastic bowls that are connected. This gives the slug a jointed and robotic movement. You can twist and spin the slug 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. Each slug has a clip so you can attach it to backpacks, bags, lanyards, and purses.
