Learn to write with this rich educational set. With the special ergonomic marker and the write-erase boards, writing becomes a game! The Montessori Pen was created based on anatomical studies, for proper ergonomics and special finger slots that have the correct grip. In the long run, the wrong grip of the pencil leads to imbalance in body posture. Additionally, if the pencil is held incorrectly, the force for producing work is used by muscles that are not needed at that moment. This will create greater fatigue in the child, who will tend to get tired easily.
