Already in the past we have developed ergonomic and helpful products together with Dr. Barbara Sattler. After long research and development the KUM Sattler Tri-Grip is now available.
The Tri-Grip favours an optimal tri-pot posture without restricting the fingers too much; the personal posture of each person is thus met. An incorrect posture is hardly possible due to the triangular shape and the position specification for the middle finger. This is supported by the nubby and arched underside. The thumb and index finger are located close to the pencil in discreet finger recesses with a reserved elevation. This ensures a pleasant writing experience.
The slanted front of the Tri-Grips provides a better view of what is written and the tip of the pen. The non-slip material ensures that you don't slip off despite the pleasantly smooth surface. On the upper side of the Tri-Grip you can see an indicated pencil which shows in which direction it should be attached to the pencil.
