A writing aid stimulates the correct finger position at the pen grip and means not only a comfortable, stable grip but also a training tool: the fingers are placed and held in a fully-fledged three-point grip, the sleek shape provides constant tactile feedback.
Reduces hand fatigue and pen pressure and prevents hypermobility in the joints of the index finger and thumb. Consistent use provides greater endurance, greater precision, and faster writing speed.
