A makeup pencil is made variable in length by use of rack shafts and a pinion. The pencil has three housings which interact to extend the brush when in use. The brush is projected out of one of the housings through a through-hole. The pencil structure has a flexible piece which seals the inside of the pencil over the through-hole when the pencil is not being used in order to prevent penetration of foreign materials in the air such as powder and dust into the pencil.
