Evoking the delicate shapes of water droplets, this necklace is made by Hario, a Japanese brand founded in 1921 that was known for producing glass coffeemakers and science instruments. Like all of their designs, this necklace is handmade with a process that involves craftspeople in Japan melting glass with a torch. Once in a molten state, the glass is formed by blowing and shaping with tools and hand movements. The resulting glass design is heatproof, with a strong resistance to temperature change and excellent durability against chemicals and shock. Hario is the only company producing heatproof glass at its own factory in Japan. The length of the Hario Water Drops “R” Glass Necklace can be adjusted freely with its sliding ball.
