A writing instrument comprises a first end portion having a writing point and a second end portion opposite to the first end portion. The second end portion is capable of bending when an external force is applied thereon and is capable of resuming its initial state when the force is relieved. The second end portion is preferably made of a resilient material. The second end portion may be a plunger that drives the writing point between an exposed position and a retracted position.
