Hario, which means The King of Glass, is a Japanese company that significantly contributes to the development of the international speciality coffee culture.

The company was founded in 1921 and specialized in producing high-quality, heatproof glassware equipment for medical uses and science laboratories. After many years of research, it successfully started to manufacture the eco-friendly Hario Glass, using 100% natural minerals to refine heatproof glass.

Since 1949, HARIO uses its know-how to create also household items, including coffee brewing products: drippers, kettles and manual grinders.
