Set of 5 pins of different head shape for various levels of difficulty in grasping and screwing by using the fingers.
The tightening / loosening action involves a three-finger grip in which the thumb is positioned to the side, while the phalanx on the middle finger opposes the index finger. The role of counterposing the middle finger to the thumb is reinforced by the support that the third finger gets from the fourth and fifth fingers. The three different head diameters provide for increasing the complexity of the task.
