Abstract
A useful writing implement which comprises an outer casing and an inner tube inserted into the outer casing for storing a plurality of presharpened leads. The outer casing has an intregrally formed protrudent flexible elongated reduced neck portion for releasably engaging an upper enlarged portion of the inner tube. The neck portion is integrally formed with a lateral triangular flat protrustion for partially covering the upper enlarged portion of the inner tube for preventing the presharpened leads from slipping out of the inner tube. The outer casing is integrally formed with a dependent leg for insertion into a longitudianl slot provided at the lower end of the inner tube, the leg being integrally formed with an inward hook-shaped portion which will be forced to extend into the slot and slide on a longitudinal slide side wall provided at the upper end of the slot, to allow the leads to fall down when the inner tube is moved downward. The inner tube can be returned to its original position to cause a new lead to be pushed into a writing position.
