After several early prototypes—including the ShanghaiTime and Solitube clocks—the Zen Clock became the first design to enter full production. Released in 2016 and produced until 2021, it marked a turning point for our business: we developed custom colon tubes specifically for it, and its success led to increased demand, allowing us to hire our first glassblower and a second team member—finally giving me time to focus on research and development.
