Did you know that aching hands and stiff shoulders can be caused by the pen you use? The Dr. Grip was developed to alleviate such problems in an ergonomic and comfortable way. The grip texture, barrel diameter, balanced weight distribution, and low-viscosity ballpoint ink all work together to minimize hand stress and fatigue. The innovative grip consists of two layers of silicone: a hard outer layer and a soft inner layer. The result is a grip that is firm but yielding, providing a good balance of cushion and support.
