From the Manufacturer
Reduces strain on neck, shoulders, and arms.
Since its launch, the Dr. Grip series has established a new field of writing instruments to reduce fatigue.In cooperation with Professor Yoshida, the Tokai University University University University University University and Affairs Design Science, "Easy to move writing instruments" were achieved based on experimental data.
Weight Balance
It focuses on the first time writing instrument.By reducing both ends of the pen, the weight is concentrated on the center of gravity that acts as the rotational axis of a writing instrument, making it easy to move.By reducing the value of inertia moment of inertia *, you can control the pen with less force and relieve the burden on your hands.
