The Dr. Grip is a 0.3 mm mechanical pencil with a quiet shake-and-click mechanism. It features a shake-lock mechanism that can be switched on or off by turning the grip. When the lock is on, the lead can still be advanced by clicking.
Features
The shake-lock mechanism helps keep the lead from extending when the pencil is jostled during transport.
Quiet design reduces the sound of clicking and shaking compared with the previous model.
Designed for comfortable writing with reduced fatigue.
