Spare lead holder
摘要:
A holder for spare lead comprises a hollow cylindrical holder body, said holder having an open end portion and a longitudinal groove formed on the inner wall along the axial direction of the holder body for locating only a suitable number of leads to a position from which the leads are taken out, and a cap body frictionally and rotatably mounted on the one end portion of the holder body. The cap body has an opening to dispense the spare lead from the groove.
