With a hook on the top of the ball pen, the Hang-on pen can be flexibly fixed on a backpack or shoulder bag. Pressing a button on the side of the pen, a special device allows the user to both unhook the hook and refill the refill. Just press this button lightly, the refill can be retracted and locked again. This beautiful and simple design is based on the observation of user behavior. The case comes from the official website of the Red Dot Award and is only shared as a winning case.
