A writing aid encourages the correct finger position when gripping the pen and not only provides a comfortable, stable grip, but also a training tool: the fingers are placed and held in a full 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 ensures greater endurance, more precision and faster writing speed.
