Bolly Balls are finger and eye hand coordination exercisers designed for use by individuals with upper extremity, fine motor, or neurological disabilities. These suction balls stick to each other, a tabletop, a large peanut, or a therapy ball using a pinching motion to create figures, designs, and patterns. The set includes plain balls, balls with faces, and suction bases for additional stability. The activity develops eye-hand coordination and increased hand strength and proprioceptive feedback. The set includes four bases, four heads, and 20 balls. DIMENSIONS: The balls are 2 inches in diameter.
