A twin type stick-shaped material extending container comprised of a base sleeve having first and second concave inner end portions at both ends of the base sleeve. First and second rotary guide sleeves are inserted into the concave inner end portions of the base sleeve. First and second traveling bodies have first and second stick-shaped material receiving bases respectively, slidably fitting in first and second rotary guide sleeves. The first traveling body is inserted in the second traveling body and inserted in the base sleeve. First and second spiral threaded grooves are formed on circumferences of the first and second traveling bodies into which first and second raised portions engage. First and second rotation prevention means regulate the direction of rotation of the first rotary guide sleeve provided on the first and second traveling bodies. The first and second rotary guide sleeves are capped with first and second inner caps respectively detachably attached to outer caps. The rotation of the first rotary guide sleeve makes first stick-shaped material receiving base slide into the first rotary guide sleeve so that a thin eraser is extended from the rotary guide sleeve according to the direction of rotation of the first rotary guide sleeve as the first stick-shaped material receiving base slides into the first rotary guide sleeve.
