Earth friendly glass brand

HARIO is a heat-resistant glass manufacturer that started in 1921. When the company was founded, it started with the manufacture of flasks and other physics and chemistry products, after the war, it manufactured coffee siphons and then expanded into the household goods field. The reason why we have consistently manufactured heat-resistant glass since our founding is that heat-resistant glass is an earth-friendly material. Not only is it resistant to heat and acid, but it does not use heavy metals at all, and it uses lead-free ink to print the glass.
