About Us

We believe that the shift to an environmentally conscious and healthy lifestyle should be joyful, easy and accessible for everyone. 


We are on a mission to develop products and services that elevate our daily rituals and are kind to the environment. To create beautiful, completely plastic free, reusable high performance products that make disposables obsolete, is a long path. It requires constant research and development, that’s why we have teamed up with research institutes and pioneering material manufacturers to create tomorrow's sustainable innovations.
