The Pyongyang Daily Necessities Factory turns out varieties of consumer goods.
Recently, it began mass-producing a new kind of portable toothbrush.
Dr. Ri Kyong Il, a workshop head of the factory, told KCNA that the toothbrush consists of case, brush and paste. The case is also used as the handle.
The new model is lower in production cost than other kinds of portable toothbrush.
The factory also produces antibiotic toothbrushes with nano-materials and functional materials.
