Fingers feel relaxed and flexible while holding the specially designed, triangular shaped grip of the SumoGrip pencil. The ergonomically correct contour is a natural fit for both adult and teen hands. Physical therapists recommend SumoGrip to carpal tunnel patients and for adults with fine motor skill difficulty.
SumoGrip 0.9mm is perfect for teens and adults who tend to press hard while writing, which restricts use in other mechanical pencils by causing lead to break and pencil tips to retract. SumoGrip 0.9mm withstands strong writing pressure because of the heavier lead and the clear, fixed lead sleeve.
