Made for children's small hands, the Twist 'N Write Mechanical Pencil is smaller than the Ergosof, making it the perfect size for elementary-sized hands. These pencils are great at home or in the classroom. The pen's wishbone-shaped body naturally shapes the fingers into the school-taught "tripod" finger grasp. The soft rubber body and curvy shape are designed for comfort, allowing kids to focus on their content without worrying about their pencil grip or writing speed. This means that they'll get just as excited about learning to write as they will about drawing pictures. The thick 2mm pencil lead never needs sharpening. Just twist the tip to expose more lead. This tub contains 48 pieces in an assortment of colors and is perfect for sharing and passing around. Helpful for Arthritis and Ehlers-Danlos Syndrome patients.
